Cn-02 Bit A

Error Counter Clear Signal

Selection

Factory

Setting: 0

For Position Control Only

Selects the pulse form of error counter clear signal CLR (1CN-15).

Setting

Meaning

0

Clears the error counter when the CLR

signal is set at high level. Error pulses

do not accumulate while the signal

remains at high level.

Cleared state

1CN-15

1

Clears the error counter only once when

the rising edge of the CLR signal rises.

Cleared only once at this point

1CN-15

3.2.3 Using Encoder Outputs

Encoder output signals divided inside the SERVOPACK can be output externally. These
signals can be used to form a position control loop in the host controller.

TERMS

Divided (or dividing)

“Dividing” means converting an input pulse train from the encoder mounted on the motor
according to the preset pulse density and outputting the converted pulse. The unit is pulses
per revolution.
