In the drive application program, overvoltage control of the drive must be disabled for
correct operation of the brake chopper. This has been done at the factory for units
with brake choppers.
WARNING! All materials near the brake resistors must be non-flammable. The
surface temperature of the resistors is high. The temperature of the air rising from
the resistors is hundreds of degrees Celsius. Protect the resistors against contact.
For resistor cable, use the type specified for drive input cabling (specified under
chapter Technical Data) so the input fuses will protect the resistor cable also. Twoconductor
shielded cable with the same cross-sectional area can alternatively be
used. The maximum length of the resistor cable is 10 m.
For protection against overheating, resistors with thermal circuit breakers (standard
in ABB resistors) should be used. The circuit breakers should be wired to the
ENABLE inputs of the brake choppers.
WARNING! The ENABLE input terminal blocks of the choppers are at intermediate
circuit potential when the supply unit of the ACS800-07 is running. This voltage is
extremely dangerous and may cause serious damage or injuries if the isolation level
and protection conditions for the thermal circuit breakers are not sufficient. The
normally-closed breakers should always be properly isolated (over 2.5 kV) and
shrouded against contact.
Note: For the ENABLE input wiring, use cable rated as follows:
ï twisted pair (screened type recommended)
ï rated operating voltage between a core and earth (U0): ? 750 V
ï insulation test voltage > 2.5 kV
Verifying the capacity of the braking equipment
1. Calculate the maximum power (Pmax) generated by the motor during braking.
2. Ensure the following condition is met:
The Pbrmax values specified in the technical data table above are for the reference braking cycle
(1 minute of braking, 9 minutes of rest). If the actual duty cycle does not correspond to the reference
cycle, the maximum allowed braking power Pbr must be used instead. In the technical data table,
Pbr is given for two additional braking cycles. See below for directions for calculating Pbr for other
braking cycles.
3. Check the resistors selection. The energy generated by the motor during a 400-
second period must not exceed the heat dissipation capacity ER.
If the ER value is not sufficient, it is possible to use a four-resistor assembly in which two standard
resistors are connected in parallel, two in series. The ER value of the four-resistor assembly is four
times the value specified for the standard resistor.
Custom resistors
Resistors other than the standard resistors can be used provided that:
ï the resistance is not lower than with the standard resistors
WARNING! Never use a brake resistor with a resistance below the value specified
for the particular drive / brake chopper / resistor combination. The drive and the
chopper are not able to handle the overcurrent caused by the low resistance.
ï the resistance does not restrict the braking capacity needed, i.e.,
where
ï the heat dissipation capacity (ER) of the resistors is sufficient for the application
(see step 3 above).
Pmax maximum power generated by the motor during braking
UDC voltage over the resistor during braking, e.g.,
1.35 · 1.2 · 415 VDC (when supply voltage is 380 to 415 VAC),
1.35 · 1.2 · 500 VDC. (when supply voltage is 440 to 500 VAC) or
1.35 · 1.2 · 690 VDC (when supply voltage is 525 to 690 VAC).
