Preliminary
Command signal connection.
The command governing the motor may be a velocity or current command.
All the command signal lines must be shielded twisted pairs and the shield must be connected to
the voltage reference at the module (pins 2, 4 or 10 of X1).
The input impedance of the velocity command is 22 kOhms (a range of ±10 V).
The input impedance of the current command is 10 kOhms (a range of ±6.2 V).
