2.1.2 Precautions on Connection
 Connections of various signals
Signal type
Point
Pulse command output
 Connect the output allocated to each channel and the command pulse input of
servo 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 servo
amplifier.
 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 user
programs 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 user
programs turn ON.
CW over limit input
Deviation counter clear
output
 Connect the output allocated to each channel and the counter clear input of servo
amplifier.
 The length of a deviation counter clear signal is specified in the range of 1 to 100
ms 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 servo
amplifiers.
