10.2.11 Brake opening signal (BRK) and brake error signal (BER)
(1) Please set brake opening signal 14 (BRK) and brake error signal 15 (BER) to an intelligent
output terminal 11~14.
(2) When using brake control function, please set BRK/BER signal to intelligent output terminal.
Set brake opening signal(BRK) for opening the brake to the output terminal. Set brake error
signal(BER) to the output terminal to use the signal which occurs under the braking error.
Note)
Please Refer to chapter 11.4 (Braking control function) for details.
10.2.12 Zero speed detect signal(ZS)
(1) Please set 16 (ZS) to an intelligent output terminal 11~14 and a relay output terminal. By
selecting zero speed signal in an intelligent output selection this function comes into effect.
(2) This function detects that the output of the rotation speed of a motor or the output of LAD fell
off from the zero speed detection level(o030) and outputs the ZS signal.
(3) This function acts to the LAD output when the control method is VC, VP1, VP2, SLV. Also, this
function acts to the output of the rotation frequency of a motor when control method is vector
control with sensor.
