Set the power and resistance of the external regenerative resistor in H02‑26 and
H02‑27.
●
Ensure the resistance of the external regenerative resistor is higher than or equal
to the permissible minimum resistance.
●
When the regenerative resistor is used at its rated power rather than the
processing power (average value) in environments within the specified
temperature range, the temperature of the resistor will rise to above 120°C under
continuous braking. To ensure safety, lower down the resistor temperature with
forced air cooling, or use a resistor equipped with a thermal switch. For the load
characteristics of the regenerative resistor, consult with the manufacturer.
Set the heat dissipation coefficient based on the heat dissipation condition of the
external regenerative resistor.

When an external regenerative
resistor is used, set H02‑24 to
a value not higher than 30% in
case of natural cooling or not
higher than 50% in case of
forced air cooling.

Higher resistor heat dissipation coefficient indicates higher braking efficiency.

Using the built‑in regenerative resistor
When P

< P
a
and E

> E
C
, use the built‑in regenerative resistor. In this case, set
H02‑25 to 0.
When using the built‑in regenerative resistor, connect terminals P⊕ and D with a
jumper bar.

Regenerative resistor not needed
When E
1
< E
C
, the regenerative resistor is not needed because the braking energy
can be absorbed by the bus capacitor. In this case, set H02‑25 to 3.
