6.1.2.2 Stop and recovery due to an internal error
1 • In an internal error status, inputting "emergency stop" has no effect.
However, release it before inputting "start ready".
2 • As per the alarm reset sequence.
3 • The holding brake timing (standard value 300 ms, in Parameter Mode 1 on page 13) can
be changed to 0 to 1 sec. However, when it is set at 0 msec, command ineffective
(forced zero) status continues for 4 msec after SON.
• The current is limited by the sequence current limit value (standard value 120 %, in
parameter Mode 1 on page 12) within 300 msec.
4 • It is possible to make commands ineffective (forced zero) for 300 msec after SON by
setting Func1 bit5 to "0" when setting parameters. In case of the position control type,
however, the command pulse remains as a deviation for 300 msec.
• It is possible to make commands effective immediately after SON by setting Func1 bit5 to
"1" when setting parameters. However, the sequence current limit value is applied when
switching from SON to SOFF and is not applied when switching from SOFF to SON.
5 • It is possible to output the command effectiveness from CN1-39 and 40 pins by using
parameter Func4.
6 • The time period from main circuit power ON to SRDY is approx. 1 sec. However, in case
of single phase power of Amplifier with 50A capacity, that will be approx. 1.5 sec.
