Control bit/value
Explanations
LD_SLOT You specify the meaning of the value in SLOT with this load request:
• 0000
B
means: No action, idle
• 0001
B
means: Period duration in μs
• 0010
B
means: On delay in μs
• 0100
B
means: Duty cycle
Values not listed are invalid and trigger setting of feedback bit ERR_LD (when MODE_SLOT =
0) or ERR_SLOT_VAL (when MODE_SLOT = 1).
SET_DQA
You use this bit to set digital output DQn.A when TM_CTRL_DQ and SET_DQB are set to 0.
SET_DQB
You use this bit to set digital output DQn.B when TM_CTRL_DQ and SET_DQA are set to 0.
TM_CTRL_DQ You enable the technological function of the digital output with this bit.
• 0 means: SET_DQA and SET_DQB define states of DQn.A and DQn.B
• 1 means: Output sequence defines the state of DQn.A; DQn.B is always 0.
SW_ENABLE You activate the software enable with this bit. If you are using the hardware enable, it is com-
bined with the software enable.
• 0 means: Stop output
• 1 means: Start output
Use of the HW enable is activated through parameter assignment. The HW enable is controlled
externally using the digital input DIn.0.
RES_ERROR You use this bit to reset the following feedback bits when errors are pending:
• ERR_24V
• ERR_DQA
• ERR_DQB
• ERR_LD
Reserved
Reserved bits must be set to 0.
