1804 Function generator operating mode
... specifies at which input the generated setpoint is entered.
= 1 Current setpoint
The current control loop is closed, all of the higher–level control loops are open.
The function generator output is the current setpoint in the current controller clock
cycle.
= 2 Disturbing torque
The speed control loop is closed, all of the higher–level control loops are open. The
function generator output is the current setpoint in the speed controller clock cycle.
When starting and stopping, the acceleration/deceleration is limited by the ramp–
function generator of the function generator.
= 3 Speed setpoint
The speed control loop is closed, all of the higher–level control loops are open. The
function generator output is the speed setpoint in the speed controller clock cycle.
When starting and stopping, the acceleration/deceleration is limited by the ramp–
function generator of the function generator.
= 4 Disturbing torque with the ramp–function generator (from SW 2.4)
The speed control loop is closed and all of the higher–level control loops are open.
The function generator output is the current setpoint in the speed controller clock
cycle.
When starting and stopping, the acceleration/deceleration is limited by the ramp–
function generator of the function generator as well as by the ramp–function gener-
ator in the speed setpoint channel. The maximum value from the ramp–up/ramp–
down time (P1256/P1257) of the RFG in the speed setpoint channel and the time of
the ramp–function generator of the function generator (P1813) is always used.
= 5 Speed setpoint with the ramp–function generator (from SW 2.4)
The speed control loop is closed and all of the higher–level control loops are open.
The function generator output is the speed setpoint in the controller clock cycle.
When starting and stopping, the acceleration/deceleration is limited by the ramp–
function generator of the function generator as well as by the ramp–function gener-
ator in the speed setpoint channel. The maximum value from the ramp–up/ramp–
down time (P1256/P1257) of the RFG in the speed setpoint channel and the time of
the ramp–function generator of the function generator (P1813) is always used.
When moving along the characteristic, the ramp–up and ramp–down time of the
ramp–function generator in the speed setpoint channel is taken into account.
Note: When a parameter is changed with the function generator active, this causes the
system to crash.
