Precautions When Not Using the Safety Function
When not using the safety function or when performing a JOG operation, use the
SERVOPACK with the safety function jumper connector (JZSP-CVH05-E, provided
as an accessory) inserted. If the SERVOPACK is used without the jumper connector
inserted into CN8, no current will flow to the motor and no torque will be output.
When Hbb is displayed on the panel operator and digital operator, the motor is base-
blocked by the safety function. Check to see if the JZSP-CVH05-E jumper connector
is correctly inserted into CN8.
Pin No.
