LD_SLOT
MODE_SLOT
SW_ENABLE
TM_CTRL_DQ
SET_DQA
SET_DQB
RES_ERROR
Meaning
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 OUTPUT_VALUE sign indicates direction of rotation (positive for forward)
and (negative 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
Your program can change the On-delay and Period duration before the start of
the output sequence using the SLOT and MODE_SLOT parameters.
0 μs to 85,000,000 μs
Interpretation of the value SLOT: All other values not listed below are invalid and
produce the error ERR_LD (in single-update mode) or ERR_SLOT_VAL (in
permanent-update mode).
Bit 3 Bit 2 Bit 1 Bit 0
0 0 0 0
0 0 0 1
0 0 1 0
Bit 4 Mode for use of the field SLOT.
0 Single-update mode
1 Permanent-update mode
Bit 0 Software enable: Start and terminate the output sequence.
0 Output canceled
0 → 1 Starts output sequence on positive edge when "Function DI" = "Input"
or "Function DI" = "External stop".
1 Enable output sequence, when start is dependent on HW enable with
"Function DI" = "HW enable"
Bit 1 The outputs are always controlled by the module in DC-motor mode.
This bit is ignored.
X Don't care: No effect on the outputs.
Bit 3 Controls the value of the digital output DQn.A, if TM_CTRL_DQ = 0.
X Don't care: No effect on the outputs.
Bit 4 Controls the value of the digital output DQn.B, if TM_CTRL_DQ = 0.
X Don't care: No effect on the outputs.
Bit 0 Reset pending errors (ERR_LD, ERR_DQA, ERR_DQB, and
ERR_24V).
0 Reset of errors is not active
1 Reset of errors is active
