External Regenerative Resistor Wiring
The user must prepare the Regenerative Resistor. When installing, the user must remove the
wiring of P1 Contact and the PC Contact of TB1 terminal and then serially connect the regenerative
resistor between P contact and PC contact. To secure personnel safety, it is recommended to use the
Resistor with Thermal Switch.
The wiring diagram is as follows:
P1
PC
P
Driver
External Regenerative Resistor
(self prepared)
TB1
Make sure the cable connecting PC and P1
terminal is disconnected
Since the regenerative resistor will generate temperature higher than 100°C when consuming
regenerative power, be sure to use heat-resistant, non-flammable wire material when connecting
regenerative resistor, and make sure that the regenerative resistor does not make contact with any
items.
