Slip compensa-
tion
n109 Slip compensa-
tion gain
Slip compensation gain is set as a per-
centage of the maximum output frequency
(n014). Use the following equations to set
a value that corresponds to the motor
rated slip.
n109 =100 ×
(Synchronization speed – rated motor
speed) ÷ synchronization speed
Synchronization speed = 120f/P
P: No. of polls
f: Rated frequency
Set n014 to the motor’s rated frequency.
Note The rated motor speed can be con-
firmed from the motor’s nameplate.
Note If n109 = 0.0, the slip compensation
function is disabled.
Note If n032 = 0.0, the slip compensation
function is disabled.

n110 Motor no-load
current
Set the motor no-load current as a per-
centage of the motor rated current (n032).
Note This
setting is used as a parameter
of
the slip compensation function.
Note Set after confirming the motor no-
load current with the manufacturer.
Alternatively,
calculate
the value from
the
current when there is no load and
when
running at the rated
frequency
.

n111 Slip compensa-
tion primary
delay time
Slip compensation primary delay time is
set in s units.
Note Usually setting is not necessary. Ad-
just when slip compensation respon-
siveness is low or when speed has
not stabilized.
When responsiveness is low, de-
crease the set value.
When speed has not stabilized, in-
crease the set value.
