ZSP will turn on when the servo motor is decelerated to 50 r/min (at 1)),
and will turn off when the servo motor is accelerated to 70 r/min again (at
2)).
ZSP will turn on when the servo motor is decelerated again to 50 r/min (at
3)), and will turn off when the servo motor speed has reached -70 r/min (at
4)).
The range from the point when the servo motor speed has reached on
level, and ZSP turns on, to the point when it is accelerated again and has
reached off level is called hysteresis width.
Hysteresis width is 20 r/min for this servo amplifier.
DO-1
Electromagnetic
brake interlock MBR When using the device, set operation delay time of the electromagnetic
brake in [Pr. PC16].
When a servo-off status or alarm occurs, MBR will turn off. DO-1
Warning WNG When warning has occurred, WNG turns on. When a warning is not
occurring, turning on the power will turn off WNG after 2.5 s to 3.5 s. DO-1
Battery warning BWNG BWNG turns on when [AL. 92 Battery cable disconnection warning] or [AL.
9F Battery warning] has occurred. When the battery warning is not
occurring, turning on the power will turn off BWNG after 2.5 s to 3.5 s. DO-1
Alarm code ACD0 (CN1-24) To use these signals, set " _ _ _ 1" in [Pr. PD34].
This signal is outputted when an alarm occurs.
When an alarm is not occurring, respective ordinary signals are outputted.
For details of the alarm codes, refer to chapter 8.
When "Enabled (absolute position detection system by DIO) (_ _ _ 1)" is
selected in [Pr. PA03] and when MBR, DB, or ALM is assigned to CN1-22
pin, CN1-23 pin, or CN1-24 pin, selecting alarm code output will generate
[AL. Parameter error].
DI-1
ACD1 (CN1-23)
ACD2 (CN1-22)
Variable gain
selection CDPS CDPS turns on during gain switching. DO-1
Absolute position
undetermined ABSV ABSV turns on when the absolute position is undetermined. DO-1
ABS
transmission
data bit 0 ABSB0 (CN1-22) This is used to output ABS transmission data bit 0. When "Enabled
(absolute position detection system by DIO) (_ _ _ 1)" is selected in [Pr.
PA03], the CN1-22 pin will become ABSB0 only during ABS transfer mode.
(Refer to chapter 12.)
DO-1
ABS
transmission
data bit 1 ABSB1 (CN1-23) This is used to output ABS transmission data bit 1. When "Enabled
(absolute position detection system by DIO) (_ _ _ 1)" is selected in [Pr.
PA03], the CN1-23 pin will become ABSB1 only during ABS transfer mode.
(Refer to chapter 12.)
DO-1
ABS
transmission
data ready ABST (CN1-25) This is used to output ABS transmission data ready. When "Enabled
(absolute position detection system by DIO) (_ _ _ 1)" is selected in [Pr.
PA03], CN1-25 pin will become ABST only during ABS transfer mode.
(Refer to chapter 12.)
