KL2502-0010
Pulse direction setting for controlling a stepper motor power unit with active interpolation.
The output terminal KL2502-0010 has the Frq-Cnt pulse mode with active interpolation as factory setting. It differs from the KL2502-0000 by a processor that is faster by a factor of four, so that all frequencies that are specified are provided with the same factor. That means:
PWML mode: | from 8 Hz to 1 kHz |
PWMH mode: | from 1 kHz to 80 kHz |
Cnt-Cnt-PWM mode: | from 1 kHz to 32 kHz |
Period duration, 1 digit corresponds to 250 ns | |
Register R37: | Pulse duration, 1 digit corresponds to 2 μs |
In addition, the power range for controlling a stepper motor has been extended:
Frq-Cnt-PWM mode: | from 8 Hz to 32,7 kHz |
Frq-Cnt-Impuls mode: | from 8 Hz to 32,7 kHz |
Interpolation
During interpolation, a start frequency F_start (R39) is specified, from which this starts. Above F_start, frequency steps specified by the controller are interpolated with the gradient specified via the maximum frequency step size F_delta (R38) and the time base T_delta (R40). F_delta and T_delta define the maximum acceleration of the drive.
Key data for stepper motor operating mode
Maximum frequency: | 32.7 kHz |
Resolution: | 8 Hz / Digit |
Impulse with: | R37 x 2 μs |
Process data
DOUT of the termina:
Number of output pulses. If the frequency setting is positive, the pulses are counted forward, if it is negative, the pulses are counted backward.
DIN of the terminal:
Frequency setting with 8 Hz/digit and sign as direction setting.
