Function:
0 s
*
[0 -
600 s]
Programmable in 1 s increments. Once the bypass
function is activated in accordance with the setting
in
parameter 24-10 Drive Bypass Function
, the
bypass delay timer begins to operate. If the
frequency converter has been set for several restart
attempts, the timer continues to run while the
frequency converter tries to restart. If the motor
has restarted within the time period of the bypass
delay timer, the timer is reset.
If the motor fails to restart at the end of the
bypass delay time, the frequency converter bypass
relay, which has been programmed for bypass in
parameter 5-40 Function Relay
, is activated.
Where no restart attempts are programmed, the
timer runs for the delay period set in this
parameter and then activates the frequency
converter bypass relay, which has been
programmed for bypass in
parameter 5-40 Function
Relay
.
