Group 1: Basic Parameters

Maximum Output Frequency (Fmax)

Settings
This parameter determines the AC motor drive's Maximum Output Frequency. All the AC
motor drive frequency command sources (analog inputs 0 to +10V and 4 to 20mA) are scaled
to correspond to the output frequency range.
Please note that output frequency may be not in this setting range due to parameter setting:
1. Pr.00.10 is set to 0: when enabling Pr.07.03 (Slip Compensation) in V/f mode, it may be not
in this setting range.
2. Pr.00.10 is set to 1: The AC motor drive will auto compensate slip in vector mode, so it also
may be not within this setting range.
Related parameters: 00.10 (Control Method), 04.12(Min AVI Frequency), 04.14(Max AVI
Frequency), 04.16(Min ACI Frequency), 04.18(Max ACI Frequency), 04.19(ACI/AVI2
Selection), 04.21(Min AVI2 Frequency), 04.23(Max AVI2 Frequency) and 07.03(Slip
Compensation (Used without PG) (Motor 0))
01.01

Maximum Voltage Frequency (Fbase) (Motor 0)

Settings
This value should be set according to the rated frequency of the motor as indicated on the
motor nameplate. Maximum Voltage Frequency determines the v/f curve ratio. For example, if
the drive is rated for 460 VAC output and the Maximum Voltage Frequency is set to 60Hz, the
drive will maintain a constant ratio of 7.66 V/Hz (460V/60Hz=7.66V/Hz). This parameter value
must be equal to or greater than the Mid-Point Frequency (Pr.01.03).
