Pin Signal name Pin Signal name
A18-A22 GND B18 Not connected
A23 Not connected B19-B22 HV+
A24-A27 PHASE1 B23 Not connected
A28 Not connected B24-B27 PHASE2

Note 1: pins marked as Not connected are left empty for to make larger clearance for high voltage signals. Leave these pins unconnected on motherboard designs.

Note 2: Each power signal is present in two pin groups (internally parallel) and these signals should be wired parallel on motherboard.

Signal assignment

General purpose I/O (GPI/GPO)

The table below summarizes the default functions for GPIO pins.

Connecting GPI/GPO's are not mandatory. All of the same functions may be also accessed via SimpleMotion V2 interface.
Signal name Function Used for Remarks
GPI1 Home switch Homing reference switch (optional), can also disable homing, or use Hard-stop homing without switch Note 1
GPI2 Enable positive feed Axis positive direction end limit switch (optional) Normally closed switch. When switch is open, motion/force in positive direction is prevented. 1
GPI3 Enable negative feed Axis negative direction end limit switch (optional) Normally closed switch. When switch is open, motion/force in negative direction is prevented. 1
GPI4 Clear faults Rising logic edge on this pin will clear fault state of drive In IONICUBE mode, also rising edge of enable signal will clear faults.
GPI5 Start homing Rising logic edge on this pin will start homing if homing is enabled
GPO1 Servo ready Use to indicate controller that drive is ready Logic 1 when drive has been initialized, enabled and ready to follow setpoint commands. If homing is enabled, then servo ready will be logic 1 after homing is successfully completed.
GPO2 Tracking error warning Use to indicate controller when drive is having difficulties following the setpoint before a tracking fault occurs Logic 1 when tracking error (position or velocity, depending on control mode) is greater than 1/8 of configured fault trigger level.
GPO3 Fault state Use to indicate controller that drive is stopped due to fault state In IONICUBE mode GPO3 goes logic 0 after when enable signal is set low (for Mach3 compatibility).
GPO4 2-way travel allowed Use to indicate controller when axis is allowed to move in both directions (i.e. any limit switches not hit or axis lies within an optional homing defined limited travel range)
GPO5 Reserved

1) Connect switch between GND and GPIn pin

Setpoint signals

Setpoint mode is selected by software with parameter CRI and behavior is affected by parameters CIS, MUL, DIV, CAO and CED.

Drive listens setpoint commands also always through SimpleMotion V2 interface regardess of CRI paramter setting.
Signal name Function Used for Remarks
HSIN1 High speed digital input 1 Depending in setpoint mode, can be either: direction input (of pulse/dir or PWM) or quadrature A input
HSIN2 High speed digital input 2 Depending in setpoint mode, can be either: pulse input (of pulse/dir), PWM input or quadrature B input
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

Feedback device signals

Signal name # Electrical type (in most feedback device modes) Alternate electrical type (in some feedback device modes) Connection with various feedback devices
HALL_W Digital input W Hall sensor input, phase W
HALL_V Digital input V Hall sensor input, phase V
HALL_U Digital input U Hall sensor input, phase U
A- Differential input A- Analog input A- Quadrature encoder (A channel)/SinCos A
A+ Differential input A+ Analog input A+
B- Differential input B- Analog input B+ Quadrature encoder (B channel)/SinCos B
B+ Differential input B+ Analog input B-
C- Differential input C- Quadrature encoder index channel (Z channel)
C+ Differential input C+
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.

Other signals

Signal name Function Used for Remarks
REGEN_OUT Regenerative resistor control output Use to control optional regenerative resistor to prevent excessive voltage generation in HV DC bus during motor deceleration. A buffer circuit is needed for resistor, such as a logic level MOSFET. See example schematic here.
MECH_BRAKE_OUT Mechanical holding brake control output Use to control optional holding brake of motor A buffer circuit is needed to drive a solenoid brake, such as a logic level MOSFET. See example schematic here.
ENABLE_IN Drive enable input signal (always required) Use to enable drive and allow motor to initialize and operate Accepts up to 24V voltage level, but works also with 3V level signal
STO2 Safe torque off input signal (always required) Use to allow motor to produce torque (activate power stage) Accepts up to 24V voltage level, but works also with 5V level signal. STO is inactive (allows torque) when logic high is supplied.

Electrical interface modes (software selectable)

IONI supports various function mappings to I/O signals and is selectable through Granity CEI Electrical interface parameter. The differences between modes are:

Mode Description Effects
Standard The default mode I/O assignments as described in pinout
IONICUBE Mode for IONICUBE that is compatible with Mach3 software
  • In addition to rising edge of GPI4, also rising edge on Enable will clear fault state. In standard mode Enable input will not clear faults.
  • GPO3 (fault state) output will go logic low after Enable signal goes low. In standard mode GPO3 stays high until faults are cleared.
