The illustration below shows the 2 types of changeover that occur after a coil changeover, (a) Y
(star) – ∆ (delta) changeover, and (b) Y (star) – Y (star) changeover. As shown in (c), one of the
contactors (MC1 or MC2) is turned ON and the other is turned OFF at all of the coil changeover
control circuits.

2-6-4 Wiring of an external emergency stop
(1) External emergency stop setting
Besides the emergency stop input from the NC or PC to spindle drive unit, double-protection when
an emergency stop occurs can be provided by directly inputting an external emergency stop to the
CN23 connector on the power supply unit. Even if the emergency stop is not input from CNC for
some reason, the contactors will be shut off by the external emergency stop input from CN23
connector on the power supply unit.

[2] Setting
When using the external emergency stop, the rotary switch on the front of the power supply unit
and the parameter (PTYP) of drive unit that controls the power supply must be set.
• Rotary switch setting: 4
• Parameter setting: Add "0040" to the setting of PTYP (SP041).

type
When external emergency stop is validated, 0040 [hex] is added to PTY P for the drive unit
connected to the power supply unit.
CAUTION
The emergency stop signal input to the CNC side cannot be used as a substitute
for the external emergency stop function (CN23).

(2) Operation sequences of CN23 external emergency stop function
If only external emergency stop is input when external emergency stop valid is set in the
parameters (the emergency stop is not input in the spindle drive unit), an "In external emergency
stop" (warning EA) will be detected. At this time, the spindle drive unit does not enter an emergency
stop status. (There will be no deceleration control.)
If an emergency stop is not issued for the spindle drive unit within 30 seconds and the setting time
of SP055 after the external emergency stop is input, the power supply unit outputs contactor shutoff
signal (MC1), and then it shuts off the contactors, and a power supply error (alarm 6F) is detected
simultaneously. If the emergency stop is input within 30 seconds and the setting time of SP055, the
warning EA replaces the "In emergency stop" (warning E7). A normal emergency stop status will
result if the contactor shutoff command is further input.
When the setting value of SP192 is set to "2" or "3", a power supply error (alarm 6F) will occur even
if the emergency stop is input within 30 seconds and the setting time of SP055.
Ready ON is possible even if CN23, an external emergency stop has been input when the
emergency stop is canceled, but a power supply error (alarm 6F) will occur after 30 seconds.
