Emb Common Run/Stop - Danfoss VLT Option Panel Instruction Manual

EMB Common Run/Stop

General Information
The common run/stop function provides
remote run and stop control of the motor(s) in
bypass. Without common run/stop, the motor
would automatically run at full speed when-
ever the bypass is activated. The remote
signal provides drive control as well as
bypass control, making this one input com-
mon to both. Common run/stop is enabled by
factory default. When used with the run per-
missive function, common run/stop permits
run request operation in bypass.
Prior to Enabling Common Run/Stop
• Complete the start-up procedure to
verify motor rotation direction in
bypass is correct and that the system
is ready in all respects for continuous
full speed operation in bypass.
Operation
• A user supplied remote start
command wired to connector X55,
terminals 3 and 4 initiates remote
bypass operation. With common run/
stop, bypass mode cannot be
activated by hand on the drive keypad
or by serial communication.
Common Run/Stop Setup
• Wire input terminals 3 and 4 on
connector X55 per the system
application.

To Disable Common Run/Stop
• Common run/stop is enabled by
factory default when ordered.
• To disable the feature, jumper termi-
nals 3 and 4 on connector X55. This
allows the bypass to start when the
bypass switch is placed in the bypass
position.
• Remove red wire from terminal 18 of
the drive control terminal and insulate
the end of the wire to prevent shorting.
This is required or the drive will always
have a run command.
• If applicable, connect remote run/stop
input to terminals 12 and 18 in the
drive.
