SEt-17 Zero Clamp Level
• Setting range: 0 to 5000 RPM
• User Default: 0
• Changes anytime
This parameter is the stop speed level in the zero clamp control mode.
If the analog speed command is below the preset value of this
parameter, the motor will decelerate and stop.
Even if the analog speed command of the controller is 0V at the speed
command offset auto adjustment, a little offset voltage can exist at the
servo drive input terminal, which may cause the motor to revolve
slowly. In this case, using the zero clamp function can prevent the
motor from revolving a little caused by the offset voltage.
If the CN1 connector pins where the zero clamp function is allocated
are ON, the voltage command below the level set at SEt-17 will be
ignored. When the value of the speed command surpasses this level
again, the motor will be accelerated to the value of the command.
If the input pins for zero clamp is not set, execute the clamp
automatically.
