V/f V/f w/PG
OLV/PM AOLV/PM
Sets the frequency of the test signal used during Inertia Tuning and ASR Gain Auto-Tuning.
Reduce this value if the inertia is large or if a fault occurs.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the amplitude of the test signal used during Inertia and ASR Gain Auto-Tuning. Reduce
this value if the inertia is too large or if a fault occurs.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the motor inertia. Default setting is the inertia of a YASKAWA motor.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the response frequency of the mechanical system connected to the motor. Oscillation may
result if set too high.
All Modes
Monitors the frequency reference. Display units are determined by o1-03.
All Modes
Displays the output frequency. Display units are determined by o1-03.
All Modes
Displays the output current.
Note: The unit is expressed in 1 A for models CIMR-A4A0930 and 4A1200.
