Function:
This parameter determines which circumstances
activate the frequency converter bypass
function.
If in normal operation, the automatic frequency
converter bypass function is activated under
the following conditions:
•
In case of a trip lock or a trip.
•
After the programmed number of
reset attempts, programmed in
parameter H-04 Auto-Reset (Times).
•
If the bypass delay timer
(parameter FB-11 Drive Bypass Delay
Time) expires before reset attempts
have been completed.
Function:
Programmable in 1 s increments. Once the bypass
function is activated in accordance with the setting
in parameter FB-10 Drive Bypass Function, the
bypass delay timer begins to operate. If the
frequency converter has been set for a number of
restart attempts, the timer continues to run while
the frequency converter tries to restart. Should the
motor have restarted within the time period of the
bypass delay timer, the timer is reset.
FB-11 Drive Bypass Delay Time
Range:
03/2016 All rights reserved.
Function:
Should the motor fail to restart at the end of the
bypass delay time, the frequency converter bypass
relay is activated, which has been programmed for
bypass in parameter E-24 Function Relay. If a relay
delay has also been programmed in
parameter E-26 On Delay, Relay, [Relay] or
parameter E-27 Off Delay, Relay, [Relay], this time
must also elapse before the relay action is
performed.
Where no restart attempts are programmed, the
timer runs for the delay period set in this
parameter and activates the frequency converter
bypass relay, which has been programmed for
bypass in parameter E-24 Function Relay. If a relay
delay has also been programmed in
parameter E-26 On Delay, Relay or
parameter E-27 Off Delay, Relay, [Relay], this time
must also elapse before the relay action is
performed.
