Stall Prevention
during Deceleration
(and Braking
Transistor
Operational
Voltage)
Sets the Stall Prevention during Decel operational
voltage and the braking transistor turn-on voltage
when a braking resistor is provided.
Note: This function is active regardless of the KEB
function status or programming.

n139 018BH
AVR Time
Parameter
Sets the time constant of the output voltage AVR
(stabilization) function. AVR function is disabled
when the set value is 0.00sec.
0.00 to
2.55sec
1.00sec
n140 018CH
Undervoltage
Detection Level
Sets the Undervoltage (UV1) trip level of the DC bus.
Normally, this setting does not have to be changed.
Note: This function is active regardless of the KEB
function status or programming.

The setting range and
the initial value are
doubled for 460V units.
n141 018DH
Operation
Selection at Power
ON
Operation can be prohibited if the run command
(forward or reverse) is present when the power
supply is turned on. This can prevent accidental
machine operation.
0: Run Permitted
1: Run Prohibited
Note: This function is active regardless of the KEB
function status or programming.
0 to 1 0
n142 018EH
Selection of
Transistor
Operation during
Stop
Selects whether the braking transistor circuit is
active when the drive stops.
0: Disabled
1: Enabled
Note: This function is active regardless of the KEB
function status or programming.
0 to 1 0
n143 018FH
KEB Compensation
Time
An Undervoltage (UV1) trip will occur regardless of
the DC bus voltage when a momentary power loss
lasts more than the KEB Compensation Time.
Note: This function is disabled when the set value is
0.00 seconds.

n144 0190H
Power Loss
Detection Relay
Delay Time
Prevents power loss recovery errors caused by a
delay in the opening of the power loss detection
relay by determining when the re-acceleration
sequence is needed. The drive monitors the status
of the KEB Command and the DC bus voltage.
Re-acceleration is made when the multi-function
input terminal and the main circuit DC bus bar
voltage are restored after the power loss detection
relay delay time elapses.
Note: A setting of 50msec will be used when the set
value is 0.0sec.

KEB
Re-acceptance
Prohibition Time
Re-acceptance of KEB operation can be prohibited
only for the specified time after re-acceleration
starts after a momentary power loss.
Note: This function is disabled when the set value is
0.00 seconds.

KEB
Re-acceleration
Time selection
Selects the KEB re-acceleration time after the KEB
Command is removed.
0: Selected acceleration time (n019, n021, n041 or
n043)

KEB
Re-acceleration
Time
Sets the KEB re-acceleration time when KEB
re-acceleration time selection (n146) is 1.
Note: This parameter is not effective when n146 is
set to 0.
