Technical data

Digital Brushless AC servo drive system - Ref.0707 MCSi-21/84
Indicators (LED's)
+5 V: LED located on top of connector X1. When lit, it indicates that the
internal +5 V are being applied.
CROWBAR (ON) / VBUS OK: Two-color (green/red) light indicator located
next to the + 5 V LED. It indicates its status according to the following table:
Push-buttons and switches
RESET: Push-button for resetting the system.
TERMINATING RESISTOR (COMMUNICATIONS): This switch located
next to the connector X1 (front of the module) may be used to connect or
disconnect the line terminating resistor in RS485 communications.
