IONICUBE connectors

X1
Dual port RJ45 connector with SimpleMotion V2 interface. For pinout, seeSimpleMotion V2 port.
X2
6 pin wire terminal for logic voltage supply, Safe torque off input, analog output and relay driver outputs.
X3
Two pin wire terminal for HV DC bus supply.
X4
Main control and setpoint signal port consisting Enable input signal, Fault output signal, pulse and direction/quadrature/PWM setpoint inputs and digital outputs for home switch status. X4 is directly wired to conform most common parallel port style pulse & direction CNC controllers.
X5
Second control and setpoint signal port. This port consists analog setpoint signal inputs and additional digital I/O.
X6
These are the feedback device connector for X (lower) and Y (upper) axis motors
X7
These are the power and holding brake output connector for X (lower) and Y (upper) axis motors
X8
These are the feedback device connector for Z (lower) and A (upper) axis motors
X9
These are the power and holding brake output connector for Z (lower) and A (upper) axis motors
X10
A connector for an optional external regenerative resistor. IONICUBE has on-board regenerative resistor that is sufficient for most installations.
IONI_X, IONI_Y, IONI_Z, IONI_A
Card-edge connectors for IONI drives
Before inserting or removing IONI drives from IONICUBE, remove all power from it and discharge it's capacitors. To discharge remaining energy (~voltage) from capacitors, short circuit GND to HV+ by a conductor and measure that there is no DC voltage left between GND and HV+ terminals. Even few volts left to HV DC bus is known to cause permanent damage to IONICUBE when drives are plugged.

Front side connectors

Front side connectors consist X6, X7, X8 and X9. These connectors are the interface towards motors (motor power and feedback devices).

X7 and X9 pinout

These are the power output and holding brake output connector for motors

Pin number Signal name AC/BLDC motor Brush DC motor Stepping motor
1 GND Ground for cable shield and an optional motor holding brake coil
2 PHASE1 U (some motors R) Armature + Coil A.1
3 PHASE2 V (some motors S) Armature - Coil A.2
4 PHASE3 W (some motors T) Armature - Coil B.1
5 PHASE4 Not connected Armature + Coil B.2
6 BRAKE Optional 24V motor holding brake coil

Motor & brake wiring schematics

  • Wiring of three phase AC servo motor. Brake is optional.

  • Wiring of Brush-DC servo motor. Brake is optional.

  • Wiring of two phase stepping motor. Brake can be fitted like in the other examples. Also 6 and 8 wire motors can be wired (the two drive coils connect always to the same PHASE outputs).

An easy way to verify correctness of two phase stepper connection: unplug the 6 pin connector and then measure resistance between phases 1-2 and 3-4. Multimeter should show the same resistance for both cases (typically 0.1 - 5 ohms). Also when measuring between phases 1-3, 1-4, 2-3 and 2-4, the multimeter should indicate open circuit.

X6 and X8 pinout

X6 and X8 are the feedback device connectors of motors

Pin # Pin name Electrical type (in most feedback device modes) Alternate electrical type (in some feedback device modes) Connection with various feedback devices
Shell GND Earth/case Feedback cable shield
1 HALL_W Digital input W Hall sensor input, phase W
2 HALL_V Digital input V Hall sensor input, phase V
3 HALL_U Digital input U Hall sensor input, phase U
4 GND Encoder supply ground
5 B- Differential input B- SinCos input B- Quadrature encoder (B channel)/SinCos/serial encoder/resolver input
6 B+ Differential input B+ SinCos input B+
7 A- Differential input A- SinCos input A- Quadrature encoder (A channel)/SinCos/serial encoder/resolver input
8 A+ Differential input A+ SinCos input A+
9 5V_OUT Encoder supply 5V output Encoder power supply
10 GND Encoder supply ground
11 GPI3 Axis negative direction end limit switch (optional) Connect normally closed (NC) limit switch between this pin and GND pin
12 GPI2 Axis positive direction end limit switch (optional) Connect normally closed (NC) limit switch between this pin and GND pin
13 GPI1 Axis home switch switch (optional) Connect normally closed (NC) limit switch between this pin and GND pin
14 C- Differential input C- Quadrature encoder index channel (Z channel)/serial encoder input
15 C+ Differential input C+

Examples of feedback device and switch wiring

  • Fully wired port with differential incremental encoder, hall sensors and switches

  • Wiring of differential incremental encoder

  • Minimal wiring of incremental encoder (single ended, no index channel)

  • Wiring of Hall sensors only (only torque mode possible)

  • Illustration of wiring limit and home switches. In addition to this, encoder and/or halls are needed.


In case of single-ended encoder, connect encoder's A, B, Z only to drive's A+, B+ and C+ and leave drive's A-, B- and C- unconnected.
With differential Hall sensor (which provides U+, U-, V+, V-, W+ and W-, connect only sensor's U+, V+ and W+ to drive's HALL_U/V/W.
Never connect sensor negative outputs (A-/B-/C-/U-/V-/W-) to GND. Connect them to drive's A-/B-/C- or leave unconnected.
Feedback devices with differential signaling may use varying naming schemes of signal pairs. For example differential signal X (which contains two electrical wires) may be denoted as: X+ and X-, or X and \X or X and X. In this Wiki we mark them X+ and X-. Some Fanuc encoders have quadrature signals named as PCA, /PCA, PCB, /PCB, PCZ and /PCZ which are equivalent to A, B and Z signal pairs.

Back side connectors

A closeup of X2, X3, X4 and X5


Never connect an Ethernet to X1. While it uses similar connector and cabling, it is electrically incompatible with Ethernet. Devices may be permanently damaged by mixing Ethernet and SimpleMotion V2.
Do now wire SimpleMotion V2 ports with crossover RJ45 cables (see details). Always use straight/non-crossover patch cables. If unsure about what is the type of your RJ45 cable, don't use it.

X2 pinout

X2 is 6 pin wire terminal for logic voltage supply, Safe torque off input, analog output and relay driver outputs.

Pin number Signal name Usage
1 GND Ground
2 24V 24V logic supply
3 STO Safe torque off input (this pin also available in X1, as defined in SimpleMotion V2 port
4 VFD 0-12V analog output where voltage level is proportional to PWM duty cycle on pin PWM on X4. PWM frequency must be between 100 and 10000 Hz.
5 RL1 Relay coil driver output 1. When RLIN1 on X4 is logic high, RL1 is pulled to GND by an open collector circuit. When RLIN1 is low, RL1 is floating (max 24V). When connecting a relay that has 24VDC coil between RL1 and supplied 24V, no external free-wheeling diode is needed. Output current rating is max 500 mA.
6 RL2 Relay coil driver output 2. When RLIN2 on X4 is logic high, RL2 is pulled to GND by an open collector circuit. When RLIN1 is low, RL2 is floating (max 24V). When connecting a relay that has 24VDC coil between RL2 and supplied 24V, no external free-wheeling diode is needed. Output current rating is max 500 mA.

X3 pinout

X3 is two pin wire terminal for HV DC bus supply.

Pin number Signal name Usage
1 GND Ground
2 HV+ Motor power supply, HV DC bus (see IONI drive voltage range spec)

If using switching power supply (SMPS) as motor power supply, external rectifier diodes are needed to protect the power supplies. See See IONI power supply schemes.

X4 pinout

X4 is main control and setpoint signal port consisting Enable input signal, Fault output signal, pulse and direction/quadrature/PWM setpoint inputs and digital outputs for home switch status. X4 is directly wired to conform most common parallel port style pulse & direction CNC controllers.

Connect X4/X5 only to 3.3V or 5V logic systems. For 24V logic the use of IONICUBE 1X is recommended

Alternative setpoint signals

Setpoint mode is selected by software with parameter Setpoint inputCRI and behavior is affected by parameters Setpoint smoothingCIS, Setpoint multiplierMUL, Setpoint dividerDIV, Setpoint offset nullingCAO and Enable direction inputCED.

Drive listens setpoint commands also always through SimpleMotion V2 interface regardess of Setpoint inputCRI paramter setting.
Signal name Function Used for Remarks
HSIN1 High speed digital input 1 Depending on setpoint mode, can be either:
HSIN2 High speed digital input 2 Depending on setpoint mode, can be either:
  • Direction signal of pulse train (in Pulse and direction setpoint mode)
  • Quadrature B channel (in quadrature setpoint mode)
  • PWM (in PWM and PWM+Dir setpoint modes)
ANAIN- Differential analog negative input Used for analog setpoint mode Setpoint voltage is the voltage difference between ANAIN+ and ANAIN-
ANAIN+ Differential analog positive input Used for analog setpoint mode

X5 pinout

X5 is a second control and setpoint signal port in addition to X4. This port consists analog setpoint signal inputs and additional digital I/O.
