Connection Of External Option Regenerative Resistor - Mitsubishi Electric MELDAS MDS-B-SVJ2 Series Specifications And Instruction Manual

2-6-2 Connection of external option regenerative resistor

Remove the short bar connected between terminals P and D, and connect the regenerative resistor
between terminals P and C.

Chapter 2 Wiring and Connection
Wiring length 5m or less
1. Always install a protective cover so that the cables, etc., do not directly
contact the regenerative resistor. Select the installation place so that foreign
matter (cutting chips, cutting oil, etc.) do not enter the regenerative resistor's
terminal block. A short-circuit between the P and C terminals could lead to
servo amplifier damage.
2. The regenerative resistor generates heat of approximately 100°C (or higher,
depending on the installation conditions). Give sufficient consideration to
heat dissipation and installation position.
3. Use flame retardant wire or provide flame retardant treatment for the wire
connected to the regenerative resistor.
1. When installing on a wall, install the regenerative resistors vertically.
2. The regenerative resistor generates heat and will reach high temperatures if
the regeneration frequency is high. Do not install on wall surfaces
susceptible to heat.
3. When installing three resistors in a row, leave a space of 100mm or more
between each unit.
4. Always use twisted pair cable to connect to the servo amplifier, and keep
the length of the wiring to 5m or less. Refer to section "7-1 Selection of wire"
for details on selecting the wire.
