MDS-D-SVJ3/SPJ3 Series Instruction Manual
2-8 Wiring of the peripheral control
2 - 41
(2) Parameter settings
When using the external emergency stop, set the following parameter to the axis to which the signal is
input (contactor control axis).
<For MDS-D-SVJ3>
【#2236(PR)】 SV036 PTYP Regenerative resistor type
bit 7-4 : emgx External emergency stop function
Set the external emergency stop function. (Do not set a value other than specified.)
0: Disable 4: Enable
<For MDS-D-SPJ3>
【#13032(PR)】 SP032 PTYP Regenerative resistor type
bit 7-4 : emgx External emergency stop function
Set the external emergency stop function. (Do not set a value other than specified.)
0: Disable 4: Enable
(3) Operation sequences of external emergency stop function
[1] Operation sequences of normal emergency stop
If the normal NC emergency stop and the external emergency stop are simultaneously input, the
operation sequence will be the same as in the case of using only the NC emergency stop.
Immediately after the emergency stop is input, deceleration control is carried out in spindle control,
and dynamic brake stop in servo control in a standard case, or deceleration control when the
parameter is set. The ready signal is turned OFF after the NC confirms all axes stop, and the
contactor control axis turns the contactor OFF.
Even when the NC emergency stop signal and the external emergency stop signal are not
simultaneously input, the operation sequence will be the same as that of the normal emergency
stop provided that both signals are input before all axes stop.
