SMC Networks LECSB2-T Series User Manual

17 - 36
17．Positioning mode (pushing operation)
17.8.6 Pushing start error
[AL7F.4 Pushing start error] occurs when there is an error in the pushing operation start method,
PERR (Pushing error) turns on, and the dynamic brake stops.
17.8.7 When pushing operation is started independently
When ST1 (start signal) is turned on by specifying a point table No. with "16" or "18" set in the auxiliary
function of point table data, PERR (Pushing error) turns on and [AL7F.4 Pushing start error] occurs. In
this case, the servo motor does not operate.
RES (reset) resets the alarm and turns off PERR (Pushing error). PERR does not turn off with ST1
(start signal).
17.8.8 When the dwell is set immediately before the pushing operation
When the dwell is set immediately before the pushing operation, [AL7F.4 Pushing start error] occurs
after reaching the pushing start position and the dwell time has elapsed, PERR (Pushing error) is
turned on, and the dynamic brake is activated. The servo motor stops.
In this case, set the dwell of the point table data immediately before the pushing operation to “0”.
RES (reset) resets the alarm and turns off PERR (Pushing error). PERR does not turn off with ST1
(start signal).
