Signal Name		Opto Input Signal Definition
Enable		CLOSED allows normal operation.
		OPEN disables the control and motor coasts to a stop.
Quit		CLOSED cancels any move in progress and the motor will decelerate (at
		parameter MOT.ACC) to rest. This input is edge triggered.
		OPEN allows position mode operation.
Fault Reset		CLOSED allows the control to be cleared or “Reset” for any of the following four
		fault conditions (provided that the cause of the fault has been removed):
		•	Overvoltage		•	Electronic Fusing
		•	Undervoltage		•	Resolver Fault

OPEN allows normal operation.

Home Flag Edge triggered input that is used to sense the “Home Position”.

Trigger Rising edge triggered input that initiates a “point-to-point move”. The move is defined by the machine inputs MaI1 - 4.

MaI1,2,3,& 4 Four machine inputs are provided. These may be used with the internal PLC software program. The internal PLC software can cause an event to occur based on the presence of these inputs.

However, more often these inputs are used to define up to 15 preset positions or point to point moves. The 16th move is always home. With this method, it is not possible to use hardware limits (CW and CCW). Therefore, software limits must be used. Software limits are only active after a homing routine has completed.

Note: Hardware limit switches may be wired in series with the “Enable” input X3–9. Then if a limit is reached, the control will be disabled.
