4.1 Controls
CAUTION
The digital frequency setpoint has been set at 5.00 Hz in the factory. It is not necessary to enter a frequency
setpoint via the D button or parameter P005 in order to test that the motor turns following a RUN command.
All settings must be entered by qualified personnel, paying particular attention to the safety precautions and
warnings.
The parameter settings required can be entered using the three parameterisation buttons (P, D and Ñ) on the front panel of the
inverter. The parameter numbers and values are indicated on the four digit LED display.
Pressing this button while the inverter is stopped causes it to start and run at the preset jog frequency. The
inverter stops as soon as the button is released. Pressing this button while the inverter is running has no
effect. Disabled if P123 = 0.
Jog
Press to start the inverter. Disabled if P121 = 0.
Press to stop the inverter. Press once for an OFF1 (see section 5.4). Press twice (or hold down) for an OFF2
(see section 5.4) to immediately remove voltage from the motor allowing the motor to coast to a halt without
ramp-down.
LED Display Displays frequency (default), parameter numbers or parameter values (when P is pressed) or fault codes.
Press to change the direction of rotation of the motor. REVERSE is indicated by a minus sign (values <100) or
the left decimal point flashing(values > 100). Disabled if P122 = 0
Press to INCREASE frequency. Used to change parameter numbers or values to higher settings during the
parameterisation procedure. Disabled if P124 = 0.
Press to DECREASE frequency. Used to change parameter numbers or values to lower settings during the
parameterisation procedure. Disabled if P124 = 0.
Press to access parameters. Disabled if P051 - P055 or P356 = 14 when using digital inputs. Press and hold
to access higher resolution for some parameters. See section 6
