SIMOTRAS HD Operating Instructions
9.5.8 Velocity signal dv/dt (K0191)
This signal specifies the change in the ramp-function generator output K0190 in the time period set in
P542.
9.6 Speed
controller

Control signals for speed controller
The control signals for "Enable speed controller droop", "Enable speed controller" and "Switch over
master/slave drive" are supplied by control word 2. The following operating modes are possible (see
also Section 8, Sheet G181):
P649 = 9: The control bits in control word 2 are input bit-serially.
The binectors selected in P684, P685 and P687 determine bits 8, 9 and 11 of control word
2 (= bits 24, 25 and 27 of complete control word), and thus the functions "Enable speed
controller droop", "Enable speed controller" and "Switch over master/slave drive".
P649
≠
9: The connector selected in P649 is used as control word 2.
Bits 8, 9 and 11 control the functions "Enable speed controller droop", "Enable speed
controller" and "Switch over master/slave drive".
Enable speed controller:
0 = Disable controller, controller output (K0160) = 0, P component (K0161) = 0, I
component (K0162) = value of connector selected in P631
1 = Enable controller
Enable droop:
0 = Droop is not active
1 = Droop is active
Switch over master/slave drive:
0 = Master drive
1 = Slave drive
When "Slave drive" is selected, the I component of the speed controller is
made to "track" such that M(set, n contr.) = M(set, limit.), the speed setpoint is set to
equal the actual speed (K0179) (enable tracking with P229).
Set I component (selection of control signal via parameter P695):
When 0
⇒
1 signal transition of selected binector, the I component is set to the setting
value (selected in parameter P631)
Stop I component (selection of control signal via parameter P696):
0 = I component enabled
1 = Stop I component
Limitation active:
This signal is in the log. "1" state when the upper or lower torque limitation is violated, the
speed limiting controller is active, the current limitation is active or when the firing angle
reaches the limit.
In this case, the I component of the speed controller is stopped.
Switch over to P controller:
The P controller function is activated (I component = 0) when the speed drops to below
the changeover value.
Enabling of function via P698
