12.8 Servo ON/OFF

12.8.1 Servo ON/OFF

The servo amplifiers connected to the QD75MH is executed servo ON or OFF.
By establishing the servo ON status with the servo ON command, servo motor
operation is enabled.

The following two types of servo ON or OFF can be used.

All axis servo ON [Y1]

Cd.100

Each axis servo OFF (Buffer memory addresses: 1551, 1651, 1751, 1851)

A list of the "All axis servo ON [Y1]" and "

Cd.100

Each axis servo OFF" is given below.

Cd.100 Each axis servo OFF

Setting value "0"

Setting value "1"

OFF

All axis servo ON: Y1

: Servo ON (Servo operation enabled) , : Servo OFF (Servo operation disabled)

[1] Servo ON (Servo operation enabled)

The following shows the procedure for servo ON.
(1) Make sure that the servo LED indicates "b".

(The initial value for "All axis servo ON [Y1]" is "OFF".)

(2) Set "0" for "

Cd.100

Each axis servo OFF" (Buffer memory: 1551, 1651, 1751,

1851).

(3) Turn ON "All axis servo ON [Y1]".

Now the servo amplifier turns ON the servo (servo operation enabled state).
(The servo LED indicates "d".)

[2] Servo OFF (Servo operation disabled)

The following shows the procedure for servo OFF.
(1) Set "1" for "

Cd.100

Each axis servo OFF" (Buffer memory: 1551, 1651, 1751,

1851). (The servo LED indicates "c".)
(If the "

Cd.100

Each axis servo OFF" set "0" again, after the servo operation

enabled.)

(2) Turn OFF "All axis servo ON [Y1]".

(The servo LED indicates "b".)

POINT

If the servomotor is rotated by external force during the servo OFF status, follow

up processing is performed.

Change between servo ON or OFF status while operation is stopped.

The servo OFF command of during operation will be ignored.

When the servo OFF is given to all axes, "All axis servo ON [Y1]" is applied even

if all axis servo ON command is turned ON to OFF with "

Cd.100

Each axis servo

OFF" set "0".
