4-6 Wiring Regenerative Resistor
This section describes the specification and connection of regenerative resistors.
Regenerative Resistors Specifications
The specifications of built-in regenerative resistor (750W to 5kW) and external regenerative resistor are as follows.
■ Built-in regenerative resistor (only for 750W)
■ External regenerative resistors
How to Connect Regenerative Resistors
Connection of regenerative resistor is described as follows. For how to select regenerative resistor, see "5-4
Regenerative Resistor Setting", page 5-23.
Wiring of regenerative resistors must be correct. Otherwise this may lead to machine damage and fire.
Regenerative resistors can be connected as follows.
■
Connecting regenerative resistor with SV-005
, SV-010
, SV-020
or SV-040
The regenerative resistor can be connected to B1/ and B2 terminals independent on the polarity.
For 100V type servo amplifier, terminal assignment is different. Do not confuse the terminals to be
connected.
