Step 8 - Verify the Setup and Adjust Switches if Required 8-3
8.1 Adjusting the Maximum Speed
The maximum speed rotary switch limits the speed reference to the unit. Regardless
of what speed reference is supplied, the unit will not command a speed greater than
the value selected by this rotary switch.
Range: 1500 RPM (50 Hz) to 3600 RPM (120 Hz)
Default: 1800 RPM (60 Hz)
To set the maximum speed:
Step 1. To increase the maximum speed, turn the maximum speed rotary switch to a
higher position number.
-or-
To decrease the maximum speed, turn the maximum speed rotary switch to a
lower position number.
Step 2. Connect the display board ribbon cable and replace the cover. Verify that all
four cover screws are in place and tightened.
Step 3. Apply AC input power.
Step 4. Set the operator’s speed reference signal to maximum.
Standard units: Use the speed potentiometer or other user-supplied
external speed reference device.
Local operator control units: Use the key to increase the speed
reference and the key to decrease the speed reference.
Step 5. Use a handheld tachometer to monitor motor speed.
Step 6. Repeat the adjustment procedure until the desired maximum speed is
obtained. Note that changes to the maximum speed setting are recognized
only while the drive is stopped.
Important: If speed is erratic or not as expected, verify that only one of the speed reference
inputs (0 to 10 VDC or 4 to 20 mA) has been wired.
!
ATTENTION: The user is responsible for ensuring that driven machinery
and all drive-train mechanisms are capable of safe operation at maximum
speed. Failure to observe this precaution could result in severe bodily
injury or loss of life.
