VLT® Encoder Option MCB 102
VLT®AutomationDrive FC 301/FC 302
Introduction
The VLT® Encoder Option MCB 102 can be used as feedback source for closed-loop control or as master source for synchronizing control. Configure the encoder option in parameter group 17-** Feedback Option, see the VLT® AutomationDrive FC 301/FC 302 Programming Guide.

Safety
WARNING
DISCHARGE TIME
The frequency converter contains DC-link capacitors, which can remain charged even when the frequency converter is not powered. High voltage can be present even when the warning LED indicator lights are off. Failure to wait the specified time after power has been removed before performing service or repair work can result in death or serious injury.
•Stop the motor.
•Disconnect AC mains and remote DC-link power supplies, including battery back-ups, UPS, and DClink connections to other frequency converters.
•Disconnect or lock PM motor.
•Wait for the capacitors to discharge fully. The minimum duration of waiting time is specified in Table 1.4 and is also visible on the product label on top of the frequency converter.
•Before performing any service or repair work, use an appropriate voltage measuring device to make sure that the capacitors are fully discharged.

Electrical Installation
NOTICE
Supply the encoder through the VLT® Encoder Option MCB 102. Avoid using external supply for the encoder.
Encoder monitor
The 4 encoder channels (A, B, Z, and D) are monitored, open, and short circuits can be detected. There is a green LED for each channel which lights up when the channel is OK.
NOTICE
To view the LEDs on the option, remove the cover. Select response to encoder errors in parameter 17-61 Feedback Signal Monitoring.
NOTICE
Maximum cable length for incremental encoder 150 m [492 ft].
