{{damage|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.}}

IONICUBE connectors[edit | edit source]

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[edit | edit source]

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[edit | edit source]

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[edit | edit source]

  • 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[edit | edit source]

X6 and X8 are the feedback device connectors of motors

Examples of feedback device and switch wiring[edit | edit source]

  • 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.

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[edit | edit source]

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[edit | edit source]

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

Pin number Signal name Usage

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[edit | edit source]

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 only to 3.3V or 5V logic circuits go any GPI, GPO and HSIN pins. Most of X4 & X5 pins are directly routed to IONI drive pins and IONI electrical ratings apply.

Alternative setpoint signals[edit | edit source]

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.
