When
Pr.80 Motor capacity
"9999," the
Pr.80 Motor capacity
setting is not changed by IPM parameter initialization. IPM parameter initialization is performed
by setting
Pr.998 IPM parameter initialization
or the parameter setting mode on the operation panel.

REMARKS
If IPM parameter initialization is performed in rotations per minute (
Pr. 998
= "1"), the frequency-related parameters not listed in
the table above and the monitored items are also set and displayed in rotations per minute.
The
Pr. 998
setting automatically changes the
Pr. 71
setting but does not change
Pr. 0 Torque boost
and
Pr. 12 DC injection brake

output for
meter
In the initial setting, 1mA is output at 75Hz from
across terminals FM and SD. (SD is a common
terminal.)
The permissible frequency load current is 2mA.
For pulse specification, 1440 pulses/s is output at
75Hz.
In the initial setting, 1mA is output at 60Hz from
across terminals FM and SD.
(SD is a common terminal.)
The permissible frequency load current is 2mA.
For pulse specification, 1440 pulses/s is output at
60Hz.
