Rockwell Automation VSM500 Integrated Drive/Motor - Manual (Page 50)

8-6 Installing and Operating the VSM500 Integrated Drive/Motor, Version 3.0
8.3.1 Power-Up Start (Position 1)
Important: If AC power is lost, the drive will restart without command when power is
returned. Under these circumstances, it is the responsibility of the user to
ensure that a dangerous condition does not exist when lost AC power returns.
The switch at position 1 enables or disables the power-up start function. When this
function is enabled, output power is applied to the motor section automatically at
power up if all power-up start permissive conditions are met. These conditions are:
• No faults are active.
• The terminal strip function loss input is closed.
• For terminal block control: In addition to the start permissive conditions listed
above, the terminal strip Start and Stop inputs must be closed.
• For local operator control: The unit will simulate a start signal edge; you do not
have to press the green
key.
Settings (Position 1):
OFF position = Power-Up Start Disabled (Default)
ON position = Power-Up Start Enabled
8.3.2 Speed Reference Select (Position 2)
Important: This applies only to local operator control units.
The switch at position 2 is used to select whether the unit gets its speed reference
from the operator controls or from the analog input terminals. If this switch is set to the
OFF position, the speed reference will come from the operator controls. If this switch is
set to the ON position, the speed reference will come from the analog input terminals,
and the
and keys are not functional.
Settings (Position 2):
OFF position = Speed Reference from Operator Controls (Default)
ON position = Speed Reference from Analog Input Terminals
!
ATTENTION: Enabling this feature causes output power to be applied to the
motor section automatically at drive power up. When this feature is enabled,
the user must ensure that automatic start up of the driven equipment will not
cause injury to the operating personnel or damage to the driven equipment.
In addition, the user is responsible for providing suitable audible or visual
alarms or other devices to indicate that this function is enabled and the drive
may start at any moment. Failure to observe this precaution could result in
severe bodily injury or loss of life.
