999 • Activated using CE1...CE4
• c01 = frequency change 0 Hz...C11
• c03 = frequency change C11...0 Hz
999
• For S-ramp accel/decel, adjust c82
999
• Automatic motor braking after
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
exceeds c20 for too long
• Correct setting = (motor nameplate current)
/ (Tmd output current rating) X 100%
• Example: motor = 6.4 amps and
Tmd = 7.0 amps; correct setting = 91%
(6.4 / 7.0 = 0.91 x 100% = 91%)
