3.31 Operation selection functions 4 (Pr. 800 to Pr. 809)
3.31.1 Control selection (Pr. 800, Pr. 451 )
z Select the inverter control system such as speed control, torque control or position control.
z When "9" is set in Pr. 800, speed control test operation can be performed even when the motor is not connected.
The speed calculation value changes to track the speed command and the transition can be checked with the
control panel and analog signal output at DA1 and DA2.
3.31.2 Torque characteristic selection (Pr. 801 )
Used to select the control method.
z Setting Pr. 800 (Pr. 451) control system selection enables the following combination using the MC signal
(mode changing).
Use terminal RT to switch to the second motor control method selection.

CAUTION
• When supplying power only across R1-S1, E.OC1 (overcurrent at acceleration) occurrs when the start
signal turns on.
• Since current is not detected and voltage is not output, monitors related to current and voltage such as
output current and output voltage, etc. and output signals do not function.
• For speed calculation, speed is calculated in consideration of Pr. 880 "load inertia ratio".

Set "26" in any of Pr. 180 to Pr. 183 and Pr. 187 (input terminal function selection). (Refer to page 150.)
When using the motor with encoder, you can select the torque characteristic.

CAUTION
• Whether the motor used is a Mitsubishi dedicated motor or motor with encoder is judged by the
setting of Pr. 71 "applied motor". Refer to page 111.
• Usually, operate in the continuous operation mode (setting value: 1)
Torque at a low speed is not sufficient in the cyclic operation mode (setting value: 0).
Note this when changing the setting.
