Display START CONTROL
The REMOTE/LOCAL LEDs indicate the current start control source. If the start control source is a remote keypad
or the network, then both LEDs will be OFF.
REFERENCE CONTROL
The AUTO/MANUAL LEDs indicate the current reference control source.
IF P113 = 0 or 2, the AUTO/MANUAL LEDs will match the AUTO LED on the 4-character display. IF P113 = 0
and no AUTO reference has been setup on the terminal strip, the MANUAL LED will turn ON and the AUTO LED
will turn OFF.
IF P113 = 1, the AUTO/MANUAL LEDS show the commanded reference control source as selected by the [CTRL]
button. If the [CTRL] button is used to set the reference control source to AUTO but no AUTO reference has been
setup on the terminal strip, reference control will follow P101 but the AUTO LED will remain ON.
UNITS LEDs
HZ: current display value is in Hz
In Speed mode, if P178 = 0 then HZ LED will be ON. If P178
> 0, the Units LEDs follow the setting of P177 when the
drive is in run (non-programming) mode.
In Torque mode, the HZ LED will be ON when the drive is in
run (non-programming) mode.
In Pid mode, the Units LEDs follow the setting of P203
when the drive is in run (non-programming) mode.
If P179 > 0, the Units LEDs will show the unit of the
diagnostic parameter that is being displayed.
%: current display value is in %
RPM: current display value is in RPM
AMPS: current display value is in Amps
/UNITS current display value is a per unit (i.e./sec,
/min, /hr, etc.)
4.2 Drive Display and Modes of Operation
Speed Mode Display
In the standard mode of operation, the drive frequency output is set directly by the selected reference (keypad, analog
reference, etc.). In this mode, the drive display will show the drive’s output frequency.
PID Mode Display
When the PID mode is enabled and active, the normal run display shows the actual PID setpoint. When PID mode is not
active, the display returns to showing the drive’s output frequency.
Torque Mode Display
When the drive is operating in Vector Torque mode, the normal run display shows the drive’s output frequency.
