Notes on pulse regeneration function
The maximum output frequency of pulse regeneration output is 4 Mpps (after multiplying by 4). Operation at a
speed exceeding this may cause faulty functioning of regeneration leading to displacement.
By Pr5.33 "Pulse regenerative output limit setup", Err28.0 "Limit of pulse replay error protection" can be issued
when reaching the limit of pulse regeneration. Note that this error message is issued by detecting the output limit
of pulse regeneration, not using the maximum output frequency. The error message may be issued when fre-
quency jumps instantaneously, depending on the rotational state of the motor such as rotational fluctuation.
・
When the output source is an encoder and the pulse output resolution per rotation is not a multiple of 4, phase Z
may not be synchronous with phase A, leading to a smaller pulse width.
・
When an incremental encoder is used, the first phase Z signal after power-up may not agree with the pulse width as
shown above. When using a phase Z signal, operate the motor by at least one rotation after power-up, make sure
that the phase Z signal has been regenerated once and use the second or later phase Z signal.
