Parameters
1609 START ENABLE 2
Selects the source of the start enable 2 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 2 signal.
• This digital input must be activated for start enable 2 signal.
• If the voltage drops and de-activates this digital input, the drive will coast to stop and show alarm 2022 on the
panel display. The drive will not start until start enable 2 signal resumes.
2…6 =
DI2…DI6 – Defines digital input DI2…DI6 as the start enable 2 signal.
• See DI1 above.
7 =
COMM – Assigns the fieldbus Command Word as the source for the start enable 2 signal. Bit 3 of the Command
word 2 (parameter 0302) activates the start disable 2 signal.
• See fieldbus user’s manual for detailed instructions.
-1 =
DI1(INV) – Defines an inverted digital input DI1 as the start enable 2 signal.
-2…-6 =
DI2(INV)…DI6(INV) – Defines an inverted digital input DI2…DI6 as the start enable 2 signal.
•See
DI1 (INV) above.
1610 DISPLAY ALARMS
Controls the visibility of the following alarms:
• 2001, Overcurrent alarm
• 2002, Overvoltage alarm
• 2003, Undervoltage alarm
• 2009, Device overtemperature alarm.
For more information, see section Alarm listing on page 258.
0 =
NO – The above alarms are suppressed.
1 =
YES – All of the above alarms are enabled.
1612 FAN CONTROL
Selects drive cooling fan control. Can be used to mitigate DC voltage fluctuations.
0 = AUTO – Fan is controlled automatically (default).
1 =
ON – Fan is always forced on.
1613 FAULT RESET
Allows to reset faults with a parameter. Can be used to reset faults from remote monitoring systems that have access
to drive parameters.
0 =
