• When the limit is reached, the
drive displays CL, and either the
acceleration time increases or the
output frequency decreases.

Note
CONFIRM MOTOR SUITABILITY FOR USE WITH DC BRAKING
DC Brake voltage (P174) is applied for the time specified by P175 with the
following exceptions:
• If P111=1, 3 and P175=999.9 the brake voltage will be applied
continuously until a run or fault condition occurs.
• If P110=2, 4…6 and P175=999.9, brake voltage will be applied for 15s
• If P121…P123=18 and the corresponding TB-13 input is CLOSED,
brake voltage will be applied until the TB-13 input is OPENED or a fault
condition occurs.

range; used to skip over frequencies
that cause mechanical vibration
• P181 and P182 define the start of
the skip ranges

both ranges.
