Description
Without stop-on contact control
Stop-on contact control
Usually set a value between 130%
and 180%.
Set the force (holding torque) for
stop-on contact control.
No compensation.
Set a PWM carrier frequency for
stop-on contact control.
(Valid at the output frequency of
3Hz or less.)
As set in Pr. 72 "PWM frequency
selection".
Set to the rated slip frequency of
the motor + about 1.0Hz.
This parameter may be set only if
Pr. 278 ≤ Pr. 282.
Generally, set this parameter to
about 50 to 90%. If the setting is
too low, the load is liable to drop
due to gravity at start.
Suppose that the rated inverter
current is 100%.
Generally, set this parameter to
about 0.1 to 0.3s.
Pr. 292 = 7: Set the mechanical
delay time until the brake is loos-
ened.
Pr. 292 = 8: Set the mechanical
delay time until the brake is loos-
ened + about 0.1 to 0.2s.
At this frequency, the brake open-
ing request signal (BOF) is
switched off. Generally, set this
parameter to the Pr. 278 setting +
3 to 4Hz.This parameter may be
set only if Pr. 278 ≤ Pr. 282.
Pr. 292 = 7: Set the mechanical
delay time until the brake is closed
+ 0.1s.
Pr. 292 = 8: Set the mechanical
delay time until the brake is closed
+ about 0.2 to 0.3 seconds.
Brake sequence function is made valid when a setting is "7 or 8".
Droop control is invalid
Set the drooping amount at the
rated torque as a percentage with
respect to the rated motor fre-
quency.
Set the time constant of the pri-
mary delay filter applied to the
torque current.
