When *FORWARD and *REVERSE are both open (signals are left floating) the spindle is off and spins
freely. However, the change from enabled (*FORWARD and/or *REVERSE on to both off) is also a
signal to stop (just like Emergency Stop); the drive is never supposed to coast to a stop.
The change from WYE to DELTA or vice versa occurs only when the drive is off (*FORWARD and
*REVERSE open) and the motor is stopped or below 50 rpm. When the CNC wants DELTA mode, the
signal WYE/*DELTA is pulled low.
When the CNC wants LOW GAIN, the signal *LO GAIN/HIGH GAIN is pulled low.
*EMERGENCY STOP and *FAULT share the same I/O pin at the amplifier. A spindle FAULT is de-
clared by the spindle drive. Status good is 10 VDC thru a 1K pull-up resistor. 0 VDC indicates a fault
condition to the CNC. The Fault output is open collector that can sink 500 mA max. When *ESTOP is
asserted (signal is pulled low), drive is to totally ignore FORWARD, REVERSE, and velocity command,
and ramp down to in stop.
