3.2 Learning to Use the Keypad
The keypad includes HAND, OFF and AUTO buttons that are described further.
3.2.1 HAND - OFF - AUTO Buttons Operation
The inverter is operable only when it is in HAND or AUTO mode. HAND mode is for local control using
the keypad, while AUTO mode is primarily for remote control via terminal strip or communications. The
inverter stops operating when it is in OFF mode. Select one of the modes (HAND or AUTO) to operate
the inverter or OFF to stop the operation.
3.2.1.1 HAND Button
The HAND button is used for local (keypad) operation of the drive. Both start/stop and speed
reference are from the Keypad. The inverter will ignore all digital inputs except for BX, External Trip,
Fire Mode and Fixed Speed inputs (Speed-L, Speed-M and Speed-H).
• Pressing the HAND button will start the inverter. The HAND button acts as a start button.
• The default speed is zero (0) Hz.
• To set speed, at the Monitor display (MON), Frequency is on Line-1. The speed can be changed at this
screen using Up, Down, Left and Right arrow buttons only. The PROG/ENT button is not required.
• The speed can be changed while running in Hand mode or while stopped (OFF button).
• Hand mode disregards the settings of DRV-06 (Cmd Source) and DRV-07 (Freq Ref Src).
• IN HAND MODE, the frequency (speed) displayed at the Monitor display (MON) is duplicating parameter
DRV-25, “HAND Cmd Freq”. The default speed is 0 Hz.
3.2.1.2 AUTO Button
The AUTO button on the keypad is primarily used to put the inverter in the ready mode for remote
start/stop operation. The AUTO button may be used to start and stop the inverter locally depending on
DRV-06 settings described below.
DRV-06 (Cmd Source) default setting is Fx/Rx-1 for remote start command.
DRV-07 (Freq Ref Src) default setting is Keypad-1 for changing speed (frequency).
• With these default settings, the AUTO button will not start the inverter.
• The inverter is looking for a remote start command at terminal P1 (IN-65 default is Fx,
Forward).
• The AUTO button must be pressed once to put the inverter in the Ready mode (Green LED
blinking).
• When the remote start command is made, the inverter will start and the AUTO LED will remain
on (solid). This is the normal running mode of the inverter.
• If a remote start command is already made (at P1) during power up, the inverter will not start.
The start command has to be deactivated (opened) and re-activated (closed) to start the
inverter.
• The speed (frequency) can be set at the Monitor display (MON). Frequency is on Line-1.
• Press the PROG/ENT button.
• Use the Up, Down, Left and Right arrow buttons.
• Press the PROG/ENT button again to save the change.
• Other remote Frequency References (DRV-07) may be used.
