Chapter 4: AC Drive Parameters
4–16
Motor Base RPM Default Setting: 1750
Range: 375 to 24,000 RPM
• This value should be set according to rated Base RPM of the motor as indicated on
the motor nameplate.
Motor Maximum RPM Default Setting: P0.03
Range: P0.03 to 24,000 rpm
• This value should be set according to the desired maximum speed of the motor.
This value should not exceed the motor’s maximum rated speed.
• This value cannot be set lower than Motor Base RPM (P0.03).
This parameter, along with P0.02 and P0.03, determines the Maximum Output
Frequency of the AC Drive. The Maximum Output Frequency can be calculated
as follows:
• If an output limit based on Maximum Output Frequency is desired, use the following
equation to determine the corresponding value for Motor Maximum RPM:
Motor Auto Tune Default Setting: 00
Settings: 00 Disable
01 Enable P0.06 only (R1)
02 Enable P0.06 and P0.07 (R1 + No-load Test)
• Auto-tuning is required only for Sensorless Vector Control Modes
(P2.10 = 02, 03, 05).
Do NOT set auto-tuning without a motor connected. Also, do NOT set auto-
tuning with any mechanical load connected to the motor output shaft.
The unit will auto detect when you press the RUN key after this parameter is set
to 01 or 02. When set to 01, the unit will auto detect only the motor R1 line to
line resistance value (P0.06); manually enter the motor no-load current in P0.07.
When set to 02, the values of both P0.06 and P0.07 will be filled in automatically.
Refer to the “Auto-Tune Procedure” subsection of chapter 3 for step-by-step auto-
tuning instructions.
P0.05
Warning: The Motor Maximum RPM parameter (P0.04) should never exceed the
maximum RPM rating for the motor you are using. If this information is
not readily available, consult your motor manufacturer.
