2.7.4 Speed preconditioning (L_NSET)
This FB conditions the main speed setpoint as well as an additional setpoint (or other signals) for the
subsequent controller structure by using a ramp generator or fixed speeds.

Variable name Data type Signal type Variable type Comment
nCInhVal_a Integer analog VAR_INPUT Here the signal is applied that the main setpoint
integrator is to accept when the controller is inhibited
(CINH).
bRfgStop_b Bool binary VAR_INPUT Holding (freezing) of the main setpoint integrator to its
current value.
bRfg0_b Bool binary VAR_INPUT Leads the main−setpoint integrator via the current
T
i
−times to 0.
bNSetInv_b Bool binary VAR_INPUT Control of the signal inversion for the main setpoint.
nNSet_a Integer analog VAR_INPUT Provided for main setpoint; other signals are
permissible.
bJog1_b Bool binary VAR_INPUT Selection and control of overriding "fixed setpoints"
for the main setpoint.
bJog2_b Bool binary VAR_INPUT
bJog4_b Bool binary VAR_INPUT
bJog8_b Bool binary VAR_INPUT
bTI1_b Bool binary VAR_INPUT Selection and control of alternative "fixed setpoints"
for the main setpoint.
bTI2_b Bool binary VAR_INPUT
bTI4_b Bool binary VAR_INPUT
bTI8_b Bool binary VAR_INPUT
nSet_a Integer analog VAR_INPUT Here the signal is applied that the main−setpoint
integrator is to accept when bLoad_b = TRUE.
bLoad_b Bool binary VAR_INPUT Control of the two ramp generators in special
situations, e.g. quick stop (QSP)
bAddInv_b Bool binary VAR_INPUT Control of the signal inversion for the additional
setpoint
