Digital Brushless AC servo drive system - Ref.0707
MCSi-19/84
DIRECT FEEDBACK
Auxiliary Feedback Input
, pins 5, 6, 36, 21, 35, 20, 4 and 3:
Input to connect
a second feedback device with TTL signals. The connector provides an
aux 5 V DC (0.5 A max) for the feedback device
(see pin 4).
ENABLES
Drive Enable input, pin 13:
No current circulates through the motor stator
winding at 0 V DC, thus it no longer supplies torque. It is activated with +24
V DC.
Speed Enable input, pin 15:
At 0 V DC, it forces an internal zero velocity
command. It is activated with +24 V DC.
Common to inputs Drive Enable and Speed Enable pin 14:
Reference
point for inputs Drive Enable and Speed Enable.
+24 V DC and 0 V DC, pins 43 and 44:
Output of the internal 24 V DC
power supply that may be used for the control of inputs Drive Enable and
Speed Enable as well as the programmable digital input. It offers a
maximum current of 50 mA limited internally.
DIGITAL INPUTS AND OUTPUTS
Programmable digital input, pins 11 and 12:
Digital input (servo drive at
+24 V DC and 0 V DC) used as input for some integrated functions.
Programmable digital output, pins 27 and 28:
Optocoupled open
collector output that reflects the output of some integrated functions.
DRIVE OK
Drive Ok, pins 29 and 30:
Relay contact that closes when the internal status
of the drive control is OK.

Note that
this relay contact must be necessarily included in the electrical
maneuver.
