APPENDICES

CP CONTROL (Continuous Path Control) CW (Clockwise)

MELSEC-Q

Continuous path is a control method in which a path is followed without interrupting such as in uniform speed control.

Rotation in the clockwise direction. Rotation in the clockwise direction looking from the motor shaft end side.

CREEP SPEED

A speed at which the machine moves very slowly.

It is difficult for the machine to stop accurately when running at high speed, so the movement must first be changed to the creep speed before stopping.

Refer to the term "NEAR-POINT DOG".

CURRENT FEED VALUE

The OP address at the completion of the machine OPR is stored.

The position currently being executed is stored.

This value changes when the current value is changed.

CURRENT LOOP MODE

One of the servo control modes in positioning. Mode which uses current for torque control. Also called the torque loop mode.

Refer to the section of "position loop mode".

CURRENT VALUE

This is the current address (position) when stopped or during positioning.

D/A CONVERTER (Digital-to-Analog converter)

A device having a function to convert the digital value expressing the No. of pulses to an analog value expressing the voltage (or current).

No. of pulses	D/A	Voltage 0 to ±10V.
0 to 80,000
pulses/second

DATA NO.

To carry out positioning to 2 or more addresses, each position is assigned a sequence No. such as No. 1, No. 2, No. 3, etc. The positioning is then carried out following this sequence. The QD75 is capable of positioning up to No. 600.

	No.2		No.4
			No.6
No.1		No.5	No.3

DECELERATION RATIO

A ratio used when the machine is decelerated using a toothed gear. This ratio is a numeral larger than 1.

Deceleration	=	Input gear speed
ratio		Output gear speed
