Method for determining regenerative resistance specification
Firstly, use the built-in resistance of the driver to run for a long time to see if it can meet the
requirements: ensure that the driver temperature d33<60
℃
, the braking circuit does not alarm
(Regeneration load factor d14<80), and the driver does not report overvoltage error
If the driver temperature is high, try to reduce the regenerative energy power, or external
resistance of the same specification (in this case, cancel the built-in resistance).
If the brake resistance burns out, try to reduce the regenerative energy power, or put an
external resistance of the same specification or even more power (in this case, cancel the
built-in resistance).
If d14 is too large or accumulates too fast, it means that the regenerative energy is too large,
and the built-in resistance cannot consume the generated energy, the regenerative energy
power will be reduced, or the external resistance with higher resistance value or power will be
reduced.
If an overvoltage error is reported by the driver, the regenerative energy power is reduced, or a
resistance with a smaller external resistance, or a parallel resistance.
Attention
Match the colors of the motor lead wires to those of the corresponding motor output terminals
(U.V.W)
Never start nor stop the servo motor with this magnetic contactor.
Cable must be fixed steadily, avoid closing to radiator and motor to prevent reducing the
properties of heat insulation
