Group 11 Auxiliary Parameters
11-00
Direction Lock Selection
Range
【0】:
Allow forward and reverse rotation
【1】:
Only allow forward rotation
【2】:
Only allow reverse rotation
If motor operation direction is set to 1 or 2, the motor can only operate in that specific
direction. Run commands in the opposite direction are not accepted.
Forward or reverse commands can be issued via the control terminals or keypad.
Parameter 11-00 can be used in fan and pump application where reverse rotation is prohibited.

Carrier frequency
Range
【
1~16
】kHz
(1)
Setting range from 1 to 16 represents kHz.
(2)
Setting range is determined by the inverter rating (13-00) and HD/ND mode (00-27).
A low carrier frequency decreases RFI, EMI interference and motor leakage current. Please refer to
the carrier frequency table 4.3.35

Refer to section 3 inverter derating based on carrier frequency.
A low carrier frequency increases motor noise but reduces motor losses and temperature.
If cable length between the inverter and the motor is too long, the high-frequency leakage
current will cause an increase in inverter output current, which might affect peripheral devices.
Adjust the carrier frequency to avoid this as shown in table 4.3.36.
Table 4.3.36 Cable length and carrier frequency

Carrier frequency
(11-01 value)
Max value 16kHz
(11-01=16kHz)
Max value 10kHz
(11-01=10kHz)
Max value 5kHz
(11-01=5kHz)
Max value 2kHz
(11-01=2kHz)
Reduce the carrier frequency if the torque does not match the speed.
