For 220V 30HP and above and 440V 40HP，the maximum output frequency is
100Hz
. ND mode is only applied to V / f and V / f + PG mode. SLV, SV, PMSV and PMSLV
modes do not provide a normal load mode.
00- 28 Command characteristic selection of master frequency
Range
【0】:
Positive characteristic (0~10V/4~20mA corresponds to 0~100%)
【1】: Negative characteristic (0~10V/4~20mA corresponds to 100~0%)
‧When inputting analog frequency reference signal from the control terminal AI1 or
AI2, select the characteristic of main frequency reference command corresponding
to the analog signal.
‧00-28 = 0: Positive characteristic of main frequency reference command.
(0-10V or 4-20mA /0-100%, -10-0V/-100%-0)
=1: Negative characteristic of main frequency reference command.
‧Please refer to Figure 4.3.10 for the characteristics of the main frequency
reference
‧ Figure 4.3.10 Positive/Negative characteristic of main frequency reference command.
00- 29 Zero-speed operation selection
Range
【0】:
Operation based on frequency command
【1】: Stop
【2】: Operation based on lowest frequency
【3】:
Zero-speed operation
In sensor vector mode (SV / PMSV) (00 - 00 = 3 / 4), when the operation frequency is
below the minimum output frequency, as shown in Figure 4.3.11.
