B. KEYPAD KEYS

LABEL FUNCTION

PRGM Pressing this key toggles between the Drive and Program modes of

DRIVE operation. Active only when the GPD 503 is in stopped condition.

JOG IN DRIVE MODE: Pressing and holding this key will initiate Jog function:

GPD 503 output goes to programmed Jog Frequency to check motor

operation, or to position machine. When key is released, output returns

to zero and motor stops. If the motor is already running, pressing this key

will have no effect.

NOTE: Disabled if the GPD 503 is programmed

to use an external JOG input.

FWD IN DRIVE MODE: Each press of this key will toggle between Forward and

REV Reverse motor run direction. The selected direction is indicated by the

FWD or REV lamp being lit. If the selection is made while the GPD 503

is stopped, it determines the direction the motor will run when started.

If the selection is changed during running, the GPD 503 will ramp the

motor to zero speed and then ramp it up to set speed in the opposite

(i.e. newly selected) direction.

RUN IN DRIVE MODE: If the GPD 503 is not programmed to operate by

external RUN and STOP signals (as indicated by REMOTE SEQ lamp

being lighted), pressing this key will produce a Run command to initiate

GPD 503 output to the motor. However, output frequency will be zero if

the frequency reference is zero at the time this key is pressed.

STOP IN DRIVE MODE: Pressing this key will produce a Stop command.

The GPD 503 will decelerate the motor in the programmed stopping

manner, then GPD 503 output will be disconnected from the motor.

DSPL IN DRIVE MODE: Each press of this key will change the display to the

next displayable parameter type available for the Drive mode. (Also see

description of

key.)

IN PROGRAM MODE: Each press of this key will change the display to

the

first

available constant number in the

list of constants

(An-, bn-, Sn- or Cn-).

DATA IN DRIVE MODE OR PROGRAM MODE: When a constant number is

ENTER being displayed, pressing this key will display the constant's set value

presently in the GPD 503 memory.

IN PROGRAM MODE ONLY: After the displayed set value has

been changed as desired, pressing this key will write the new set value

into GPD 503 memory to replace the old value.
