Connection
6.10 Connecting the regeneration resistor (sold separately)
If vertical drive (gravitational operation) such as elevator applications is performed or if sudden start-stop operation
of a large inertia is repeated frequently, use the regeneration resistor
EPRC-400P
(sold separately) or
RGB100
(sold
separately).
Install the regeneration resistor in a location where heat dissipation capacity equivalent to a level achieved with a heat
sink [made of aluminum, 350×350×3 mm (13.78×13.78×0.12 in.)] is ensured.
An available regeneration resistor varies depending on the output power. Refer to the USER MANUAL for details.
Note
Assign the TH input to the input terminal of CN5 when using the regeneration resistor.
Connection method
•
Regenerative current flows through the two thick lead wires (AWG 18: 0.75 mm
2
) of the regeneration resistor. Connect
them to the RG1 and RG2 terminals of CN1.
•
The two thin lead wires (AWG 22: 0.3 mm
2
) of the regeneration resistor are the thermostat outputs. Connect them to
the TH input assigned to CN5 and IN-COM1.

Note
•
The TH input is not assigned to CN5 at the time of shipment. When using the regeneration resistor, change the “IN input
function selection” parameter to assign the TH input. Refer to the USER MANUAL for details.
•
When the TH input is assigned to CN5, if the power consumption of the regeneration resistor exceeds the allowable
level, the thermostat will be triggered to generate the regeneration resistor overheat alarm. If the regeneration resistor
overheat alarm is generated, turn off the power and check the details of error.
•
When an external power supply is used for a power supply for input signals, turn on the external power supply before
turning on the driver main power supply.
1. Assigning the TH input to CN5
Change the “IN input function selection” parameter
to change the assignment of input signals.
Refer to the USER MANUAL for how to change.
2. Connecting the thermostat output to CN5
The figure shows an example when the TH input is
assigned to the IN8 terminal in the speed control
mode to use the built-in power supply.
Refer to the USER MANUAL when using an external
power supply.
