10-01: Prevention of Reverse operation
0: Reverse command is enabled
1: Reverse command is disabled
10-01=1, the reverse command is
disabled
.
10-02: Keypad Operation with Up/Down Keys in Run Mode
0:‘Enter’ must be pressed after frequency change
with Up/Down Keys on keypad.
1: Frequency will be changed directly when Up/Down Keys are Pressed

Note:
1. In applications where there is excessive audible noise from the motor or it is required to
reduce electrical interference (RFI) from the inverter caused by use of long cable then
the carrier frequency can be adjusted. To reduce electromagnetic interference due to long cable etc,
decrease carrier frequency. To reduce motor audible noise, increase carrier frequency.
2. The carrier frequency as minimum should be set higher than ten times the max running frequency.
Example: If the Max running frequency=400Hz, then set the carrier Frequency higher than 4 KHz.
If the Max running frequency =300Hz, then set the carrier frequency higher than 3 KHz.
