What does resetting the input ON on the FB37 OutputMM4_DP do to the MICROMASTER 4 connected?

  • Entry
  • Associated product(s)

Description:
The MICROMASTER provides the parameter option for OFF1 of keeping the pulses present for a certain period of time (P2168).
This is not possible when used with FB37 OutputMM4_DP, because when switching off OFF1 (via the block input ON = 0 => Control word bit 0 = 0) it also triggers the pulse inhibitor (control word bit 3 = 0).

Notes:

  • The time configured in the MICROMASTER 4 via parameter P2168 until inhibition of the inverter pulse is therefore not effective, because the pulses are already inhibited by the control word.
  • Remedy: Use the FB OutputUniversal (FB 36), which specifies the speed setpoint and program the delay via the user program.
