Rockwell Automation VSM500 Integrated Drive/Motor - Manual (Page 53)

Step 8 - Verify the Setup and Adjust Switches if Required 8-9
8.3.6 Stop Type (Position 6)
The switch at position 6 selects how the motor will stop when the Stop input is
asserted (or the red
key is pressed). A coast-to-rest stop turns off the transistor
power device drivers. A ramp-to-rest stop continues to switch the transistor power
device drivers until the output frequency equals 0 Hz (decelerating the motor at a rate
based on the accel / decel switch setting), and then turns off the power device drivers.
Settings (Position 6):
OFF position = Coast-to-Rest (Default)
ON position = Ramp-to-Rest
8.3.7 Reverse Disable (Position 7)
The switch at position 7 enables or disables reverse rotation of the motor. It is
factory-set to enable a forward-to-reverse change of motor direction. If this switch is in
the ON position, the reverse direction is disabled (locked out). In other words, the
motor can run in the forward direction only.
Settings (Position 7):
OFF position = Reverse Enabled (Forward/reverse change allowed; default)
ON position = Reverse Disabled (Reverse direction prohibited)
8.3.8 Minimum Speed Select (Position 8)
The switch at position 8 is used to select whether the minimum speed will be 0 RPM
(0 Hz) or will be determined by the preset inputs (terminals 8, 9, and 10 on the control
terminal block).
Important: Slide switch position 8 defines whether terminals 8, 9, and 10 are used as
presets (default) or to define the unit’s minimum speed (user option). If you
select the ON position (Minimum Speed from the Control Signal Terminal
Block), you cannot use the speed reference presets. See section 7.5.1 for
information about the preset speed inputs.
Settings (Position 8):
OFF position = 0 RPM (0 Hz) Minimum Speed (Default)
ON position = Minimum Speed from the Control Terminal Block
!
ATTENTION: The VSM500 unit can operate at and maintain zero speed.
The user is responsible for assuring safe conditions for operating
personnel by providing suitable guards, audible or visual alarms, or other
devices to indicate that the drive is operating or may operate at or near
zero speed. Failure to observe this precaution could result in severe
bodily injury or loss of life.
