6.2.3 MCH INPUTS & OUTPUTS
The drive has two analog inputs (0-10 VDC and 4-20 mA) that can be used for speed
reference, PID setpoint reference, or PID feedback. A speed potentiometer (10,000
Ohm) can be used with the 0-10 VDC input.
There are also two analog outputs: one is proportional to speed (frequency), and the
other is proportional to load.
The standard MCH drive has three programmable outputs for status indication: one
Form C Relay and two open-collector outputs.
