WARNING!
Do not set above rated motor current as listed on the motor dataplate. 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.
Commissioning
999 • Automatic motor braking below 0.1 Hz
by means of motor DC current for the
entire holding time (afterwards: U, V,
W inhibited)
• Confirm motor suitability for use with
DC braking
999 When 10 VDC is output at terminal 62, it
will equal this value (see c11)
Use c08 to scale signal
Example: c11 = 1 and c08 = 100:
At 50 Hz, terminal 62 = 5 VDC
At 100 Hz, terminal 62 = 10 VDC
Only used with DB option
100
• Triggers
current exceeds c20 for too long
• Correct setting = (motor nameplate
current) / (smd output current rating)
X 100%
• Example: motor = 6.4 amps and smd
= 7.0 amps; correct setting = 91%
(6.4 / 7.0 = 0.91 x 100% = 91%)
