Setting
70 Soft-PWM setting
You can choose whether Soft-PWM control is
to be exercised or not.
When Soft-PWM is valid, you can change the
metallic motor tone into an unoffending
complex tone.
0: Soft-PWM invalid
1: Soft-PWM valid
1
71 Applied motor
Set the motor to be used.
0: Thermal characteristic for Mitsubishi
standard motor
1: Thermal characteristic for Mitsubishi
constant-torque motor
0
72
PWM frequency
selection
You can change the PWM carrier frequency.
Increasing this value reduces the tone, but
increases noise and leakage current.
The setting is in [kHz].
0: 0.7kHz, 15: 14.5kHz
0 to 15
1
73
0-5V/0-10V
selection
You can set the input voltage specification of
terminal "2".
0: For 0 to 5VDC input
1: For 0 to 10VDC input
0
74
Input filter time
constant
Valid for eliminating noise of the frequency
setting circuit.
A lar
er set value increases the time constant.

75
Reset selection/PU
stop selection
You can choose the function of the
STOP
RESET
key
on the operation panel.
0: Reset normall
enabled/PU stop ke
disabled
In other than PU and combined operation modes
1: Enabled at reset alarm occurrence only/
PU stop key disabled
In other than PU and combined operation modes
14: Reset normally enabled/normally
decelerated to stop
15: Enabled at alarm occurrence only/normally
decelerated to stop
14
76
Cooling fan
operation selection
You can control the operation of the cooling
fan built in the inverter. (Operates in power-on
status.)
0: The fan normally operates at power-on of
the inverter.
1: The fan is normally on during inverter
operation. The fan switches on/off
according to the temperature during a stop
of the inverter whose status is monitored.
1
77
Parameter write
disable selection
You can choose whether to enable or disable
parameter write.
0: Write is enabled only during a stop in the
PU operation mode
1: Write disabled (except some parameters)
2: Write during operation enabled (external
mode and during operation)
0
78
Reverse rotation
prevention selection
You can prevent trouble during reverse
operation due to false input of the start signal.
0:
Both forward rotation and reverse rotation enabled
1: Reverse rotation disabled
2: Forward rotation disabled
0
