IONICUBE connectors and pinouts

Connector layout and naming

Power and feedback ports of X, Y, Z and A axis

Names of power and feedback ports. I.e. X9A means upper floor connector of X9 and X9B the lower floor of X9.

X2

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).
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).

X3

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