Mitsubishi Electronics MR-J2S- A instruction manual Speed setting in speed control mode

3. SIGNALS AND WIRING

(3)Speed setting in speed control mode

(a)Speed command and speed

The servo motor is run at the speed set in parameter No. 8 (internal speed command 1) or at the speed set in the applied voltage of the analog speed command (VC). A relationship between analog speed command (VC) applied voltage and servo motor speed and the rotation directions determined by the forward rotation start signal (ST1) and reverse rotation start signal (ST2) are as in (a), (1) in section 3.4.2.

Generally, make connection as shown below:

Servo amplifier

		SP1
		SG
	2k	P15R
2k		VC
Japan resistor		LG
		SD
RRS10 or equivalent

(b) Speed selection 1 (SP1) and speed command value

Use speed selection 1 (SP1) to select between the speed set by the internal speed command 1 and the speed set by the analog speed command (VC) as indicated in the following table:

(Note) External input signals

SP1

Speed command value

0Analog speed command (VC)

1Internal speed command 1 (parameter No. 8)

Note.0: SP1-SG off (open) 1: SP1-SG on (short)

The speed may also be changed during rotation. In this case, it is increased or decreased according to the value set in parameter No. 11 or 12.

When the internal speed command 1 is used to command the speed, the speed does not vary with the ambient temperature.

(c)Speed reached (SA) As in Section 3.4.2 (2).
