2.1 Connections with Servo Motor Amplifier2-32.1.2 Precautions on Connection Connections of various signalsSignal type PointPulse command output Connect the output allocated to each channel and the command pulse input ofservo amplifier. Connect a resistor (2 kΩ) for limiting currents. Use twisted-pair cables for the connection.Home input Connect the input allocated to each channel and the Z phase input of servoamplifier. Use twisted-pair cables for the connection.Near home input Connect the near home sensor to an arbitrary input. It will be valid when the outputs (Y850 to Y853) allocated to each channel in userprograms turn ON.CCW over limit input Connect the over limit switches to arbitrary inputs. It will be valid when the outputs (Y860 to Y867) allocated to each channel in userprograms turn ON.CW over limit inputDeviation counter clearoutput Connect the output allocated to each channel and the counter clear input of servoamplifier. The length of a deviation counter clear signal is specified in the range of 1 to 100ms in the “Parameter setting” dialog box of Configurator PMX.Servo on output Connect an arbitrary output of PLC to the servo on input of servo amplifier.KEY POINTS• Use twisted-pair cables for the connection between the unit and servoamplifiers.
