4.3.6 Menu "DECELERATING"
Contents: In menu "Decelerating", the decelerating ramp is defined. In addition, it is possible to optimize
the positioning reaction.
Figure 4.12 Menu structure Figure 4.13 Consequence of the parameters
Description of the parameters:
A_NEG
Presetting of the negative
acceleration - deceleration.
R_NEG1
Canging the upper or lower
R_NEG2
rounding, if necessary. A greater
value causes a smoother rounding.
V_BR
Speed at which the brake comes in.
M_NB
Size of the after-braking torque.
S_DI1
Distance at which the driving
S_DI2
command "V1", "V2" and "V3" is
S_DI3
switched off time delayed from
the control device.
If the speed falls below speed V_BR, relay "MB"
switches off. In the period of time until the
mechanical brake is really closed, the DC-
winding of the motor is supplied with a DC-
voltage, the pre-braking torque M_NB.
This voltage is switched off after a preset time
(/ZA-INTERN/T_NB) and the relay is released. If
the control switches the main contactor with this
contact, it is guaranteed that the opening of the
main contactor is effected currentless.
4.3.7 The menu "CONTROLLER"
In menu "Controller" it is possible to adjust the intervention of the speed regulator by means of the
parameter DYN. If the value is too low, it is possible to have noticeable standard tolerances at the speed
transfers. Normally, the setting range is between 70 and 100 %.
