Wiring overview. R is regenerative resistor and E is encoder. In minimum working connection, wire 5V voltage to ENABLE and STO2 inputs into X4 pins (these two signals allow drive to be operated). Note: STO2 accepts voltage from 4.5 to 25 VDC but other digital inputs, such as ENABLE only between 2.7 to 5.5VDC.

Motor & brake wiring schematics[edit | edit source]

Note: the images below are drawn for IONICUBE 4 axis version. IONICUBE 1X wiring is equivalent except there is no brake output in the X3. Brake output pin is located in X4.

Regenerative resistor[edit | edit source]

Regenerative resistor is optional and may be connected between REG and HV+ terminals. The on board transistor is capable of carrying max 10 Amp current on regenerative resistor, so minimum allowed resistance can be calculated from: Rmin=HVvoltage/10. I.e. with 48VDC HV supply, the minimum resistance is 48V/10A = 4.8 Ohms. Suggested resistor power capability is 20-100 W.

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

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.

Pin number in header Signal name Typical usage Signal name Typical usage
1 GND Ground 2 5V_OUT 5V output for optional external circuity
3 HSIN2 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)
4 HSIN1 Depending on setpoint mode, can be either:
5 ANAIN+ +/-10V analog setpoint input2 6 ANAIN- +/-10V analog setpoint input2
7 GPI2 Enable positive feed (also in X2)1 8 GPI1 Home switch input (also in X2)1
9 GPI4 Clear faults1 10 GPI3 Enable negative feed (also in X2)1
11 REGEN_OUT Regenerative resistor power switch state (redundant, IONICUBE 1X has internal power switch) 12 GPI5 Start homing1
13 MECH_BRAKE_OUT Mechanical holding brake output3 14 GPO5 Reserved for future use1
15 GPO4 Limit switch output 16 GPO3 Fault on any axis or E-stop (active low)1
17 GPO2 Tracking error warning1 18 GPO1 Servo ready1
19 STO2 Safe torque off input (this pin also present in X14) 20 ENABLE Enable drive (with or without chargepump) (this pin also present in X14)

1) For detailed pin function and alternative functions in various modes, refer to IONI connector pinout

2) Setpoint voltage is measured from the difference of voltage potentials between ANAIN+ and ANAIN-. Both ANAIN inputs must always lie within +/-12V from GND (meaning that controller's zero voltage reference, i.e. GND must be connected to the GND if drive to prevent voltage potentials from floating.

3) This output can directly drive a 24V solenoid brake (max 500mA) if VCC is supplied by 24 volts. In such case, connect brake wires between MECH_BRAKE_OUT and VCC.

4) The same pin is routed also to X1 connectors. Use ENABLE/STO2 pins of only either X4 or X1, not both.

X1 connector[edit | edit source]

X1 connectors are for SimpleMotion V2 bus which is used for drive configuration with Granity software and control over a multidrop capable serial data link. For pinout, see SimpleMotion V2 port.

DIP Switch S1 settings[edit | edit source]

On board switch S1 controls the SM bus termination. Set switch 1 to ON position if the IONICUBE 1X devie is the only device in a SM bus OR if it's the last device in device chain. All other cases, leave it OFF (in other words, if IONICUBE is chained to multiple SM bus devices and it's not the last device of the chain).

Using 24 Volt control signals[edit | edit source]

As many industrial environments use 24V signaling for logic, interfacing IONICUBE 1X has been designed to accept these voltages with help of external circuits:

  • The GPOx outputs are NPN open collector type the pulling pin to GND when output is logic 1. GPO can be loaded up to same voltage level with logic supply voltage.
    • If 24V logic accepts such NPN open collector output, wire directly
    • If push/pull type output is needed, wire a pull-up resistor (i.e. 2200 Ohm or higher) between GPOx and 24V voltage
  • Inputs are routed directly to IONI input pins that accept up to 5V directly. To extend the range, add a resistor divider network to reduce the voltage to accepted level. I.e. on each pin:
    • 470 Ohm resistor from GPIx to GND, and
    • 2200 Ohm GPIx to user 24V input signal
    • That two-resistor circuit will reduce 24V level logic 1 to an acceptable ~4.2V level, while logic 0 will be ~0V.

Dimensions and mounting[edit | edit source]

IONICUBE 1X can be mounted by screws to a base or with optional DIN rail clips to a standard DIN rail.

To mount in DIN rail, obtain 2 pcs of Phoenix Contact part number 1201578. Such part is available from many distributors including Digikey 277-2296-ND
