When execution has
terminated
abnormally
(1) The PMC on the host NC sets a function code, command data 1,
and command data 2, then sends the ST signal to the servo
amplifier module. Upon receipt of the data, the servo amplifier
module returns the operation completion signal OPC 1 to the host
NC, and also outputs the unclamp command signal to the host NC.
(2) When unclamp completion notification is sent from the host NC,
the servo amplifier unit returns the operation completion signal
OPC 2 to the host NC, then starts movement.
If positioning for the skip function (function code 8) is issued, the
skip function with the skip signal (HDI) is enabled. When HDI is
input, axis movement is stopped immediately.
