Clr (Position Deviation Clear) Signal Function And Settings - YASKAWA SGD7S series Product Manual

6.6.2 CLR (Position Deviation Clear) Signal Function and Set-
tings
The CLR (Position Deviation Clear) signal is used to clear the deviation counter in the SERVO-
PACK.
As long as the CLR signal is ON, the deviation counter will be 0, so a position loop will not be
formed.
Deviation counter
The deviation counter counts the deviation between the reference input pulses and the feedback
pulses from the encoder (i.e., the accumulated pulses).

Setting the Form of the CLR (Position Deviation Clear) Signal
You set the CLR signal form to use to clear the deviation counter in Pn200 = n.X (Clear

The pulse width of the CLR signal must meet the following condition.
Information
• If Pn200 = n.X is set to 0 or 2, the width of the CLR signal must be at least 250 μs to
• If Pn200 = n.X is set to 1 or 3, the width of the CLR signal must be at least 20 μs to
Setting the Clear Operation (Pn200 = n.X)
This parameter determines when the position error should be set to zero according to the con-
dition of the SERVOPACK. Set Pn200 = n.X (Clear Operation).

Clear position deviation at a base block (at

Do not clear position deviation. The position
deviation is cleared only with CLR (Clear Posi-
tion Deviation) signal.
Clear position deviation when an alarm occurs.
