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

999 When 10 VDC is output at terminal 62, it
will equal this value (see c11)

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

fault when motor
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%)
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.
