Mitsubishi FR - S500 instruction manual Applied motor, Voltage input selection, Set the motor used

2.10.3 Applied motor

Set the motor used.

POINT

When using the Mitsubishi constant-torque motor, set "1" in Pr. 71 for either V/F control or automatic torque boost control.

The electronic overcurrent protection is set to the thermal characteristic of the constant-torque motor.

When you selected the Mitsubishi constant-torque motor, the values of the following parameters are automatically changed. (For factory settings only)

Pr. 0 "torque boost", Pr. 12 "DC injection brake voltage", Pr. 46 "second torque boost"

Parameter	Name	Factory Setting	Setting Range	Remarks
71	Applied motor	0	0, 1	Setting is enabled when Pr. 30 = "1"

<Setting>

Refer to the following list and set this parameter according to the motor used.

Pr. 71 Setting Electronic Overcurrent Protection Thermal Characteristic

0Thermal characteristics matching a standard motor

1Thermal characteristics matching the Mitsubishi constant-torque motor

CAUTION

Set this parameter correctly according to the motor used.

Incorrect setting may cause the motor to overheat and burn.

2.10.4 Voltage input selection

You can change the input (terminal 2) specifications in response to the frequency setting voltage signal. When entering 0 to 10VDC, always make this setting.

Parameter		Name	Factory	Setting	Remarks
			Setting	Range
73		0-5V/0-10V	0	0, 1	Terminal 2 input voltage	Setting is enabled
		selection			0: 0-5VDC input	when Pr. 30 = "1"
					1: 0-10VDC input
	CAUTION						2
The acceleration/deceleration time, which is a slope up/down to the
acceleration/deceleration reference frequency, is not affected by the change in
Pr. 73 setting.

When connecting a frequency setting potentiometer across terminals 10-2-5 for operation, always set "0" in this parameter.
