SECTION 7: Keypad Operating Functions
This chapter discusses basic keypad operating functions. The keypad allows the user to enter one of four
modes: LOCAL, REMOTE, PROGRAMMING, or MONITORING.
LOCAL MODE
Turn on the power source (MCCB). The drive will display OUTPUT FREQUENCY 0.0Hz.
Press the LOCAL/REMOTE button so that the local/remote LED is on. The illuminated LED
indicates that the drive is receiving run/stop commands from the keypad (LOCAL mode).
Set the operating frequency pressing the 'up arrow' or 'down arrow' keys. Notice that display
changes to FREQUENCY COMMAND.
Press READ/WRITE to save frequency. Display changes back to OUTPUT FREQUENCY.
When the RUN key is pressed, the drive will output a frequency that will increase according to
the set acceleration time. The panel control LED will blink to indicate motor is running.
When the STOP/CLEAR key is pressed, the drive outputs a frequency that will decrease
according to the set deceleration time. The motor will decelerate and stop.
If the power switch is turned off while the drive is running a motor, the motor will coast to a stop.
This method should be used for emergency stopping only.
The output frequency can be changed while running by pressing
up arrow
or
down arrow
key.
When one of these keys is pressed the LCD display will blink, indicating that the value is being
changed. When the desired frequency is shown on the display, press the READ/WRITE key. The
output frequency will change even if the READ/WRITE key is not pressed. However, if power is
removed and the READ/WRITE key has not been pressed then the 'new' frequency will be lost
because it was not written into the EEPROM.
LOCAL MODE: FORWARD/REVERSE CHANGE
In LOCAL mode, motor direction can be changed on the fly from the keypad if Item 25,
DIRECTION SELECTION (FORWARD/REV)is set to "1" (its default):
Press READ/WRITE and
up arrow
at the same time to forward direction command ( drive will
briefly display MOTOR RUN DIRECTION: FORWARD).
Pressing READ/WRITE and
down arrow
at the same time results in a reverse direction command
(drive will briefly display MOTOR RUN DIRECTION: REVERSE).
Reverse runs can be disabled via Item 5, REVERSE OPERATION DISABLE (see page 8-1).
LOCAL MODE: JOG
To jog from the keypad, program Item 108, JOG RUN FREQUENCY and Item 109, JOG STOP
METHOD as desired (see page 8-9).
In LOCAL mode and with display of OUTPUT FREQUENCY, press PRG twice. Drive displays
FORWARD JOG MODE (PRESS RUN). Direction can be changed with up/down arrows.
Pressing RUN starts jog. Releasing RUN stops jog according to Item 109, JOG STOP METHOD.
CAUTION
Avoid frequent starting and stopping of the H3 by
turning the (MCCB) power on and off. This will shorten
the life of the drive.
