Method for select regenerative resistance specification
⚫
Firstly, use the built-in resistance of the drive to run for a long time to see if it can meet the requirements:
ensure that the drive temperature d33<60℃, the braking circuit does not alarm (Regeneration load factor
d14<80), and the drive does not report overvoltage error
⚫
If the drive 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 drive, the regenerative energy power is reduced, or a resistance
with a smaller external resistance, or a parallel resistance.
The recommended regenerative resistance specifications for the iSV2 series are as follows：
10Ω+/-5%, 100w RXFB-1,
Part num Code : 10100469
⚫ 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.
