Notes
The time between a positive edge of the DIn.0 digital input and DQn.A digital output (DQ follows
DI state). Assign the On-delay in μs directly using the OUTPUT_VALUE control interface field.
The time between a negative edge of the DIn.0 digital input and its output on the DQn.A digital
output (DQ follows DI state). Assign the Off-delay in μs with control interface parameter SLOT,
after setting up MODE_SLOT (0 or 1) and LD_SLOT = 3.
Frequency output at the digital output DQ. Assign the frequency in real format as Hz using the
OUTPUT_VALUE control interface field. The possible range is dependent on the "High Speed
Output" configuration.
High Speed Output disabled
•
Frequency (OUTPUT_VALUE): 0.02 Hz to 10,000 Hz
High Speed Output enabled
•
Frequency (OUTPUT_VALUE): 0.02Hz to 100,000Hz
The time from the start of the output sequence to the output of the frequency. Assign the On-
delay in μs with control interface parameter SLOT, after setting up MODE_SLOT (0 or 1) and
LD_SLOT = 2.
The OUTPUT_VALUE determines the duty cycle (pulse duration/period duration ratio) within a
period (PWM). The period duration can be adjusted. The new output value is applied at the next
rising edge of the output. The sign indicates direction of rotation (positive for forward) and (nega-
tive for backward).
S7 analog output format: value range is -27,648 to +27,648
DInt data type: Only 2 least significant bytes are used
For channel 0: bytes 2 and 3
For channel 1: bytes 14 and 15
The time from the start of the output sequence to the output of the frequency. Assign the On-
delay in μs with control interface parameter SLOT, after setting up MODE_SLOT (0 or 1) and
LD_SLOT = 2.
A rising edge on DIn.0 will stop the output sequence and stop the DC motor.
