• The brake release output signal to control the brake of a motor must come from the servo unit driv-
ing that motor.
• The UPS module must not be used to power other than those units shown in Fig. 4.1.
• Wire between the Alarm terminals and an I/O module as necessary.
• Interlock the BKX relay as necessary by externally adding an interlock signal to the brake release
output signal.
• It is the responsibility for the customer to provide the emergency stop switch and its wiring.
• It is the responsibility for the customer to provide the X121 connector (37-pin D-Sub female con-
nector) and related wiring.
• The SVMX, ESPX, and BKX relays must be 24 VDC miniature relays (preferably LY-2 from
OMRON).
4.2.2 UPS module timer setting
The UPS module must have its timer set so that the 24 VDC power supply will be available
for a certain period even after a blackout occurs (to earn time necessary for memory data to
be transferred to a hard disk). The relationship between timer setting and covered period is
shown below. The covered period should be at least 85 seconds.

 Position of the timer switch elements
1 means ON, 0 means OFF, and x means any position (irrelevant).
If switch element 1 is set to the OFF position, the UPS module supplies power as long as the
supplied voltage is above the low battery level.
