1. Resistor time constant specification must be > 85 seconds.
WARNING! Never use a brake resistor with a resistance below the minimum value
specified for the particular drive. The drive and the internal chopper are not able to
handle the overcurrent caused by the low resistance.
Symbols
R – Minimum allowed braking resistor.
MIN
R – Maximum resistance allowed if maximum braking torque is necessary.
MAX
P Duty-cycle based resistor power rating in deceleration braking, where "x" is
rx –
ON

Installing and Wiring Resistors
All resistors must be installed outside the drive module in a place where they can
dissipate heat.
Warning! The surface temperature of the resistor is very high and air flowing from
the resistor is very hot. Materials near the brake resistor must be non-flammable.
Provide protection from accidental contact with the resistor.
To ensure that the input fuses protect the resistor cable, use resistor cables with the
same rating as used for the power input to the drive.
The maximum length of the resistor cable(s) is 10 m (33 ft). See the "Power
Connection Diagrams" on page 15 for the resistor cable connection points.
