Control Panel Descriptions (continued)

Change Direction
Pressing this key will cause the drive to ramp down to
0 Hz and then ramp up to set speed in the opposite
direction. The appropriate Direction Indicator will
illuminate to indicate the direction of motor rotation.
Refer to [Logic Mask] and [Direction Mask]. Note
that the factory default for control of the reverse
function is the reverse input at the TB2 control
terminal block. To enable the HIM control of the
reverse function, change Bit 0 of the [Direction
Mask]
parameter to “0” to disable the reverse
function at TB2.

Direction LEDs (Indicators)
These LEDs illuminate to indicate the direction of
motor rotation.

Increment/Decrement Arrows

(only available with digital speed control)

Pressing these keys will increase or decrease the HIM
frequency command. An indication of this command
will be shown on the visual Speed Indicator LEDs.
The drive will run at this command if the HIM is the
selected frequency reference. See [Freq Select 1/2].

Pressing both keys simultaneously stores the current
HIM frequency command in HIM memory. The
Speed Indicator LEDs will flash momentarily to
indicate a successful save (if speed is above 20
percent). Cycling power or connecting the HIM to the
drive will set the frequency command to the value
stored in HIM memory.

If the Analog Speed Potentiometer option has been
ordered, the Increment/Decrement keys and Speed
Indicator will be replaced by the pot.

Speed Indicator LEDs

(only available with digital speed control)

Illuminates in steps to give an approximate visual
indication of the commanded speed.

If the Analog Speed Potentiometer option has been
ordered, the Increment/Decrement keys and Speed
Indicator LEDs will be replaced by the pot.
