10 DRIVE OPERATION
Before operating the drive, read Section 10.3, below, for instructions on the Keypad Operation.
See Figure 3, on page 16, for the keypad layout. The 4-digit display can indicate various
functions of the drive: Set Frequency, Motor RPM, Output Current and Voltage, Custom Units,
Function Numbers, Function Codes or Values, and Fault Codes. See Section 11, on page 52.
See Section 12, on page 54, for information on programming the drive. If an error message
appears while programming the drive, see Section 11, on page 52.
10.1 START-UP PROCEDURE
After the drive has been properly setup and all connections completed, the start-up procedure
can begin. If the AC power has been properly brought to the drive, the LEDs will indicate the
drive's status, as described in Table 4, on page 17. See Section 11, on page 52, for the Digital
Readout Codes.
To start the drive, press the RUN Key. The motor will begin to accelerate to the Set Frequency.
The factory set frequency is 05.00 Hz.
10.2 LOCAL/REMOTE OPERATION
The drive can be used for Local (Keypad) or Remote Operation. In this mode, the drive
frequency setting can be toggled between the Keypad and a process signal using the
LOCAL/REMOTE Key.
To disable the Local/Remote toggling feature, see Function 2.03, on page 57.
Note: The drive will power up in the mode it was set in before it was powered off. If the drive
was in Local (Keypad) Operation (factory setting), it will power up in Local (Keypad) Operation. If
the drive was set for Remote Operation, it will power op in Remote Operation.
Application Note: The STOP Key will always stop the drive whether it is in Local (Keypad)
operation or Remote Operation.
WARNING! The STOP Key is never to be used as safety disconnect since it is
not fail-safe. Use only the AC Line for this purpose.
10.3 KEYPAD DESCRIPTION
The Keypad has eight (8) keys, which are used to program drive functions. The eight (8) LEDs
provide indication of the drive’s operational status. A Main Speed Potentiometer is also provided
to set the Drive Frequency (Function 2.00 set to "0001"). See Table 4, on page 17.
Note: To avoid damage, never operate the keypad with a screwdriver or other sharp-ended tool.
