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. 3.In the vector control mode, set carrier frequency lower than 6K, to reduce noise,
set random carrier frequency mode(10-04 = 2)
10-04 : Carrier mode selection
=0 : Carrier mode0 3-phase PWM modulation
=1 : Carrier mode1 2-phase PWM modulation
=2 : Carrier mode2 2-phase randomized PWM modulation
1. 10-04=0 : Carrier mode0 is recommended in environments where low noise is required.
Correct ambient temperature and cooling is necessary.
2. 10-04=1 : Carrier mode 1 is recommended in locations where fan or pumps is required.
3. 10-04=2 : Carrier mode 2
Help to slow down the temperature raise, prolong life-span of IGBT
and control electromagnetism noise.
Note: When the inverter is running at high speed and high carrier frequency is selected then,
please set 10-04=1 this can reduce the IGBT switching losses (heat loss).
