Operating Instructions
SIMOVERT MASTERDRIVES
During normal operation, the three CBL status LEDs (red, yellow and
green) light up synchronously and for the same length of time
(flashing)!
The stationary status of an LED (ON or OFF) indicates an unusual
operating status (parameterization phase or fault!)
During normal operation, the green CC-Link-LEDs are continuously lit.
The yellow one is off!
