YASKAWA TM.V1000.01 V1000 Drive Installation & Start-Up Manual (Preliminary 01-19-07)
Description
Sets stopping method when the motor
temperature analog input
(H3-02 or H3-10 = E) exceeds the OH4 fault
level (2.34V).
0: Ramp to Stop
1: Coast to Stop
2: Fast-stop
This parameter adjusts the filter on the motor
temperature analog input
(H3-02 or H3-10 = E). Increase to add stability,
decrease to improve response.
Determines whether or not to hold the
electrothermal value when the power supply is
interrupted.
0: Disabled
1: Enabled
L2: Momentary Power Loss
Enables and disables the momentary power
loss function.
0: Disabled - Drive trips on (UV1) fault when
power is lost.
1: Power Loss Ride-Thru Time - Drive will
restart if power returns within the time set in
L2-02.
2: CPU Power Active - Drive will restart if
power returns prior to control power supply
shut down.
Sets the Power Loss Ride-Thru time. This
value is dependent on the drive capacity. Only
effective when L2-01 = 1.
Sets the minimum wait time for residual motor
voltage decay before the drive output
reenergizes after power loss ride-thru. After a
power loss, if L2-03 is greater than L2-02,
operation resumes after the time set in L2-03.
Sets the time for the output voltage to return to
the preset V/f pattern after speed search
(current detection mode) is complete.
