Classic
Fault drive, open collector output max. 50mA
Normally closed, opens when the drive in protection mode
2.1
FAULT output
(M1 signal terminal pin 1)
With a voltage (example from a CNC output) you can command the drive in torque mode.
Applying a signal of +/-10V at REQ, the Drive to supply positive or negative peak current.
The formula to determine the value of Voltage to apply in REQ in order to obtain requested current is
the following:
Example: (Drive size 10/20A, request current 8A)
NOTE:
In current reference the loop of internal velocity automatically excludes itself .
2.2
Current request (REQ)
V(REQ) = 10 * Request current / PKcurrent Drive
V(REQ) = 10 * 8 / 20 = 4V
