T echnical description 8100_ A
51
If, for example, the terminals E1, E3, E4 and E5 are assigned for the Ti enable, E1
corresponds to the first terminal, E3 to the second terminal, E4 for the third terminal
and E5 to the forth terminal in the following table:
For operation via the operating unit or the LECOM interface, you can enter the
desiredpairof ramp times with C130.
7.6.13 RAMP FUNCTION GENERATOR STOP C131
This function stops the ramp function generator for set-value 1.
The additional deceleration time for quick stop and the additional set-value are not
affected.
Incaseofterminalcontral,C131 shows the state of the digitalinput. Incase of
operation via the operating unit 8102BB er the LECOMinterface, the ramp function
generator is stopped with C131
.
7.6.14 RAMP FUNCTION GENERATOR INPUT = ZERO C132
This function resets the ramp function generator for set-value 1. The drive then
decelerates with the activated deceleration to zero.
For terminal control, C132 shows if the function "ramp function generator input =
zero" is active or not.Incase of operation via the operating unit 8102BB or LECOM
interface, the ramp function generator is set to zero with C132
= -1-.
7.6.15 CHARACTERISTIC OF RAMP FUNCTION GENERATOR C134
The ramp function generator characteristic -linear or S-shaped- is selected using
C134.
An S-shaped characteristic enables a jerk-free acceleration for short Ti times. The S-
shape is not maintained if the set-value (C046) is changed during the
acceleration/deceleration and does not refer to the additional set-value.
7.6.16 THRESHOLD FOR CHOPPING FREQUENCY REDUCTION TO 1 KHZ C 143
Thebest smooth running with low speeds is obtained with a chopping frequency of
1 kHz. WithC143, you can enter the field frequency, below which the chopping
frequency is reduced automatically to this value.
