maintaining constant speed while this signal is ON
Binary-encoded position select, bit 1 (LSB)
Binary-encoded position select, bit 2 (LSB)
Binary-encoded position select, bit 3 (MSB)
the inverter stops the zero-return operation in progress
Starts a zero-return operation (load moves toward the zero-
return point)
Limits the forward rotational torque to 10%; for use at the end
of travel in position control mode
Limits the reverse rotational torque to 10%; for use at the end
of travel in position control mode
Causes the inverter to perform only speed control (ignores
encoder pulses) while in position control mode
Pulse counter input
Clears the pulse count
(input ignored)
