WARNING!
Maximum setting is rated motor current (see nameplate). Does not provide full motor
protection!
00 00 Speed Compensation
Reduces the allowable continuous current
when operating below 30Hz.
01 No Speed Compensation
Example: Motor is cooled by forced
ventilation as apposed to shaft mounted,
self cooling fans.

WARNING!
Automatic starting/restarting may cause damage to equipment and/or injury to
personnel! Automatic starting/restarting should only be used on equipment that is

• Triggers fault when motor
current exceeds c20 for too long
• Correct setting = (motor
nameplate current) / (Tml
output current rating) X 100%
Example: motor = 6.4 amps
•
and Tml = 7.0 amps;
correct setting = 91%
(6.4 / 7.0 = 0.91 x 100% = 91%)

See also c43 and c70
If c42 = 2 or 3, the controller will start
the motor speed search at C11, or at
the last output frequency before the
fault, depending on the setting of c43
• If C14 = 4...7, motor calibration
must be performed, but C86...
C91 must be programmed first
(see C14)
• If motor calibration is attempted
before programming C86...C91,
triggers n1d fault
c60 = 1 allows the keys
adjust speed setpoint (c40) while
monitoring c61
