Ramp function generator (RFG)

Skip frequency 1 (entered in Hz)
p1091 = ...
Defines skip frequency 1, which avoids
effects of mechanical resonance and
suppresses frequencies within +/- p1101
(skip frequency bandwidth).
Skip frequency 2
p1092 = ...
Skip frequency 3
p1093 = ...
Skip frequency 4
p1094 = ...
Skip frequency bandwidth
p1101 = ...
(entered in Hz)
p1120 = ... Ramp-up time
(enters the accelerating time in s)
p1121 = ... Ramp-down time
(enters the deceleration time in s)
Rump-up initial rounding time
p1130 = ...
(entered in s)
p1131 = ... Ramp-up final rounding time
(entered in s)
Rump-down initial rounding time
p1132 = ...
(entered in s)
Ramp-down final rounding time
p1133 = ...
(entered in s)
Rounding type
p1134 = ...
0 Continuous smoothing
1 Discontinuous smoothing
p1135 = ... OFF3 ramp-down time
Defines ramp-down time from maximum frequency to standstill for OFF3 command.

The rounding times are recommended as
abrupt responses can be avoided therefore
reducing stress and damage to the mechanical
0.00 s
system.
The ramp-up and ramp-down times are
0.00 s extended by the component of the rounding
ramps.
