START ENABLE 1
-5…7 1 4
Selects the source of the start enable 1 signal.
Note: Start enable functionality differs from the run enable functionality.
0 = NOT SEL – Allows the drive to start without an external start enable signal.
1 = DI1 – Defines digital input DI1 as the start enable 1 signal.
• This digital input must be activated for start enable 1 signal.
• If the voltage drops and de-activates this digital input, the drive will coast to stop
and show alarm 2021 START ENABLE 1 MISSING on panel display. The drive
will not start until start enable 1 signal resumes.
2…5 = DI2…DI5 – Defines digital input DI2…DI5 as the start enable 1 signal.
• See DI1 above.
7 = COMM – Assigns the fieldbus Command word as the source for the start enable 1
signal.
• Bit 2 of the Command word 2 (parameter 0302 FB CMD WORD 2) activates the
start disable 1 signal.
• See fieldbus user’s manual for detailed instructions.
-1 = DI1(INV) – Defines an inverted digital input DI1 as the start enable 1 signal.
-2…-5 = DI2(INV)…DI5(INV) – Defines an inverted digital input DI2…DI5 as the start
enable 1 signal.
• See DI1(INV) above.
