Table A.1 F7 Parameter List (Continued)
Description
Sets the output level when the pulse train input is 0Hz as a
percentage of maximum output frequency E1-04.
Sets the pulse train input filter time constant in seconds.
Select the pulse train monitor output terminal MP function (value of
the part of U1- ). See Table A2 for the list of U1
monitors.
Sets the number of output pulses when the monitor is 100% (in Hz).
Set H6-06 to 2, and H6-07 to 0, to make the pulse train
monitor output synchronous to the output frequency.
Motor Overload
Sets the motor thermal overload protection (OL1) based on the
cooling capacity of the motor.
0: Disabled
1: Standard Fan Cooled (< 10:1 motor)
2: Standard Blower Cooled (≥ 10:1 motor)
3: Vector Motor (≤ 1000:1 motor)
Sets the motor thermal overload protection (OL1) time. A larger
L1-02 time will increase the time before an OL1 fault will occur.
Sets operation selection when the motor temperature analog input
(H3-09 = E) exceeds the OH3 alarm level (1.17V)
0: Ramp to Stop
1: Coast to Stop
2: Fast-Stop
3: Alarm Only
Sets stopping method when the motor temperature analog input
(H3-09 = 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 (H3-09 = E). Increase to add stability, decrease to improve
response.
Power Loss Ridethru
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.*
* In order for a restart to occur, the run command must be
maintained throughout the ride thru period.
Sets the power loss ride-thru time. This value is dependent on the
capacity of the Drive. Only effective when L2-01 = 1.
Sets the minimum time to wait to allow the residual motor voltage
to decay before the Drive output turns back on during 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 it takes the output voltage to return to the preset V/F
pattern after speed search (current detection mode) is complete.
Sets the Drive's DC Bus undervoltage trip level. If this is set lower
than the factory setting, additional AC input reactance or DC bus
reactance may be necessary. Consult the factory before changing
this parameter setting.
Sets the time required to decelerate to zero speed when a KEB com-
mand is input from a multi-function input.
Set the time (in seconds) to accelerate to the set speed after
recovery from a momentary power loss. If setting = 0.0, then active
acceleration time is used instead.
