Mitsubishi Electronics MR-J2S- A Selection of control mode, Position control mode Power on

4. OPERATION

4.2 Startup

WARNING Do not operate the switches with wet hands. You may get an electric shock.

Before starting operation, check the parameters. Some machines may perform unexpected operation.

CAUTION During power-on for some after power-off, do not touch or close a parts (cable etc.) to the servo amplifier heat sink, regenerative brake resistor, the servo motor, etc. Their temperatures may be high and you may get burnt or a parts may damaged.

Connect the servo motor with a machine after confirming that the servo motor operates properly alone.

4.2.1 Selection of control mode

Use parameter No. 0 to choose the control mode used. After setting, this parameter is made valid by switching power off, then on.

4.2.2 Position control mode

(1)Power on

(a)Switch off the servo-on (SON) signal.

(b)When main circuit power/control circuit power is switched on, the display shows "C (Cumulative feedback pulses)", and in two second later, shows data.

(2)Test operation 1

Using jog operation in the test operation mode, make sure that the servo motor operates. (Refer to Section 6.8.2.)

(3)Parameter setting

Set the parameters according to the structure and specifications of the machine. Refer to Chapter 5 for the parameter definitions and to Sections 6.5 for the setting method.

Parameter No.	Name	Setting			Description
	Control mode, regenerative brake		3	0
0					Position control mode
	option selection
					MR-RB12 regenerative brake option is used.
		0	02
1	Function selection 1				Input filter 3.555ms (initial value)
					Electromagnetic brake interlock signal is not used.
					Used in incremental positioning system.
			1	5
2	Auto tuning				Middle response (initial value) is selected.
					Auto tuning mode 1 is selected.
3	Electronic gear numerator (CMX)		2		Electronic gear numerator
4	Electronic gear denominator (CDV)		1		Electronic gear denominator

After setting the above parameters, switch power off once. Then switch power on again to make the set parameter values valid.
