0 to 50% Used to set the rated motor slip.
0.01% 9999
9999 No slip compensation
Used to set the response time of slip
compensation. When the value is made
smaller, response will be faster. However,
0.01s 0.5s 0.01 to 10s
as load inertia is greater, a regenerative
overvoltage (E.OV ) error is more liable
to occur.
Slip compensation is not made in the
0 constant output range (frequency range
above the frequency set in Pr.3)
1 9999
Slip compensation is made in the constant
9999
output range.
The motor is coasted
to a stop when the
0 to 100s
preset time elapses
after the start signal
is turned off.
When 1000s to
1100s is set (Pr. 250
setting-1000)s later,
1000 to
the motor coasts to
1100s
stop.

When the start signal
is turned off, the
motor decelerates to
stop.
