(1) Connection of Regenerative Resistor Unit
If the spindle motor is decelerated to a stop after servo retraction has been performed using the retraction function
at power failure, the regenerative resistor unit (R-UNIT6,7) is required. When connecting the regenerative resistor
unit, wire it according to "9.1.3 Connection of Regenerative Resistor Unit (1) Connection of Regenerative Resistor
Unit".
(2) Connection of Capacitor Unit
Study the control panel design using the following connection methods as reference for the power backup unit and
capacitor unit. Connect with the wire whose size is HIV22sq or more and wire the connection wires so that the two
wires closely contact with fixing bands. The connection length between the power backup unit and capacitor unit
should be 10m or less.
CAUTION
1. Only the designated combination can be used for the power backup unit and the capacitor unit.
There is a risk of fire, so always use the designated combination.
2. Connect the power backup unit's TE4(C+,C-) to the capacitor unit's TE1(C+,C-), and do not reverse the polarity.
3. When using multiple capacitor units, connect with TE2 (C+,C-) of capacitor units.
10m or less
Fixing band
Maximum number of connecting units: 6
