SEt-17 Zero Clamp Level<br />

• Setting range: 0 to 5000 RPM<br />

• <strong>User</strong> Default: 0<br />

• Changes anytime<br />

This parameter is the stop speed level in the zero clamp control mode.<br />

If the analog speed command is below the preset value of this<br />

parameter, the motor will decelerate and stop.<br />

Even if the analog speed command of the controller is 0V at the speed<br />

command offset auto adjustment, a little offset voltage can exist at the<br />

servo drive input terminal, which may cause the motor to revolve<br />

slowly. In this case, using the zero clamp function can prevent the<br />

motor from revolving a little caused by the offset voltage.<br />

If the CN1 connector pins where the zero clamp function is allocated<br />

are ON, the voltage command below the level set at SEt-17 will be<br />

ignored. When the value of the speed command surpasses this level<br />

again, the motor will be accelerated to the value of the command.<br />

If the input pins for zero clamp is not set, execute the clamp<br />

automatically.<br />
