Mitsubishi Electronics FR-A500 Manuel D’Utilisation

72

We recommend the following parameters to be set by the user.

Set them according to the operation specifications, load, etc.

1

Maximum frequency

Used to set the maximum and minimum output frequencies.

2

Minimum frequency

7

Acceleration time

Used to set the acceleration and deceleration times.

8

Deceleration time

44

Second acceleration/deceleration 
time

45

Second deceleration time

110

Third acceleration/deceleration time

111

Third deceleration time

9

Electronic thermal O/L relay

Used to set the current of the electronic overcurrent protection to protect the 
motor from overheat.

14

Load pattern selection

Used to select the optimum output characteristics which match the 
application and load characteristics.

71

Applied motor

Used to set the thermal characteristics of the electronic overcurrent 
protection according to the motor used.

73

0-5V/0-10V selection

Used to select the specifications of the frequency setting signal entered 
across terminal 2-5 to perform operation with the voltage input signal.

156

Stall prevention operation selection

For the lift application, make setting to disable high-response current 
restriction. Otherwise the torque may not be generated, rersulting in the lift 
drop with gravity. 

900

FM terminal calibration

Used to calibrate the meters connected across terminals FM-SD and AM-5.

901

AM terminal calibration

902

Frequency setting voltage bias

Used to set the magnitude (slope) of the output frequency relative to the 
frequency setting signal (0 to 5V, 0 to 10V or 4 to 20mA DC) as desired.

903

Frequency setting voltage gain

904

Frequency setting current bias

905

Frequency setting current gain
