6.1.2 Stop Sequence
6.1.2.1 Stop and recovery due to emergency stop input
1 • Release "emergency stop" before inputting "start ready".
2 • 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) between t2 and t3.
3 • It is possible to make commands ineffective (forced zero) during t3 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 t3.
• 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.
4 • If an emergency stop occurs in a heavy load status, MPE (Main circuit Power Error,
alarm "9") may be activated.
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.
7 • When the alarm generates, assemble the safety circuit outside of the amplifier.
Running away, injury, burning, fire, and secondary damage may be caused.
