0.0 0.0 {s} 999
0.0 = not active
999 = continuous brake
• 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

Configuration -
Analog output (62)
0 0 None
1 Output frequency 0-10 VDC 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
2 Output frequency 2-10 VDC
3 Load 0-10 VDC
4 Load 2-10 VDC
5 Dynamic braking
Only used with DB option

• Triggers 0C6 fault when motor
current exceeds c20 for too long
• Correct setting = (motor nameplate
current) / ( smd output current rating)

•
Example:
motor = 6.4 amps and
smd
= 7.0 amps; correct setting = 91%
(6.4 / 7.0 = 0.91 x 100% = 91%)
WARNING!
Do not set above rated motor current as listed on the motor dataplate. Does not
provide full motor protection!

Example: Motor is cooled by
forced ventilation as apposed to
shaft mounted, self cooling fans.
