8.6 Operating Using Position Control(3) Clear Signal Form SelectionTypeSignalNameConnectorPin NumberInput CLR CN1-15 Clear Input/CLR CN1-14 Clear InputNameThe internal processing of the SERVOPACK for the clear signal can be set to either of four types by parameterPn200.1. Select according to the specifications of the machine or host controller.Parameter Description TimingPn200 n.0 Clears at high level.Position error pulses do not accumulate while thesignal is at high level.(Factory setting)n.1 Clears at the rising edge.n.2Clears at low level.Position error pulses do not accumulate while thesignal is at low level.CLR(CN1-15)CLR(CN1-15)Clears athigh levelHighClears here just once.CLR(CN1-15)Clears at low leveln.3Clears at the falling edge.CLR(CN1-15)LowClears here just once.The following are executed when the clear operation is enabled.• The SERVOPACK error counter is set to 0.• Position loop operation is disabled.→ Holding the clear status may cause the servo clamp to stop functioning and the servomotor to rotate slowly due to driftin the speed loop.When the clear signal (CLR) is not wired, the signal is always at low level (does not clear).When the clear signal (CLR) is not used and CN1-14, 15 are not wired, the CLR input terminals (CN1-14, 15) are always athigh level. The SERVOPACK is Pn200.1 factory set to clear position error pulse at high level. Even if a pulse train referenceis input with the setting in this state, the pulses will be constantly cleared and the motor will not operate. Set theparameter to a value other than Pn200 = n.0, or short-circuit CN1-14, 15.(4) Clear Operation SelectionThis parameter determines when the error pulse should be cleared according to the condition of the SERVO-PACK, in addition to the clearing operation of the clear signal (/CLR). Either of three clearing modes can beselected with Pn200.28ParameterDescriptionPn200 n.0 Clear the error pulse at the /CLR signal input during the baseblock. (Factory setting)“During the baseblock” means when the SVON signal or the main circuit power supply isOFF, or an alarm occurs.n.1 Do not clear the error pulse. Clear only with the /CLR signal.n.2 Clear the error pulse when an alarm occurs or the /CLR signal is input.8-49
