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 (Y70 to Y75) 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 (Y80 to Y8B) 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.
● Use twisted-pair cables for the connection between the output of the unit and servo amplifiers.
