Register description
KL5121 11
Terminal-specific register description
Process variables
R0-R3: Pulse for speed correction of channels 1-4
R4-R7: No function
Manufacturer parameter R17-R30: Not used
Application parameter R32: Feature register:
This register describes the (hardware) settings for channels 1-4 [0x0062]
Feature Bit No. Description of the operating mode
Bit 0 0/1 0: encoder operating mode with 4-fold
evaluation [0]
1: up/down counter (pulse generator) with A as
counter input and B as U/D input
Bit 1 0/1 Latch input:
0: rising edge is ignored
1: evaluate rising edge as start signal [1]
Bit 2 0/1 Latch input:
0: falling edge is ignored [0]
1: evaluate falling edge as start signal
Bit 3 0/1 0: the outputs are switched according to positive
logic [0]
1: the outputs are switched according to
negative logic
Bit 4 0/1 0: watchdog timer active [0]
1: watchdog timer active. If the terminal does not
receive any process data from the K-bus for
100 ms the outputs are reset.
Bit 5 1 1: workpiece sensor input (latch) is active [1]
when there is a positive level at the enable
input (gate)
Bit 6 1 1: workpiece sensor input (latch) is active [1]
when there is a negative level at the enable
input (gate)
Bit 7-11 - Not used, don't change
Bit 12-15 0000
0001 Pulse operation (R33-R35 activated) [0000]
Line operation (not yet implemented)
R33: Pulse duration Ti for channel 1
[0x01F4] = 0.5 ms
Ti specifies pulse duration for the pulsed operation mode of channel 1 [
µ
s]
R34: Hold-up time Tv for channel 1
[0x1388] = 5 ms
The pulses counted in the hold-up time Tv are included in the calculation of
the speed correction [
µ
s]
R35: Period Td for channel 1
[0x4E20] = 20 ms
Period Td for the channel 1 nozzle test
R40-R43: Channel 2 register
R48-R51: Channel 3 register
R56-R59: Channel 4 register
