Step 4     Controlling the motor speed with 
a potentiometer

A potentiometer can be used to control the running 
speed of the inverter. This is achieved by varying the 
voltage applied to the analogue input. Connect the 
potentiometer to the control terminals shown below. 
Starting and stopping of the motor may be achieved 
by connecting a switch to the digital input terminals 
shown.

P006  Set to 1 to allow analogue input
P007  Set to 0 to enable control via digital input

The following parameter settings are required

To get the best performance from your drive, 
you should enter information from your motor 
ratings plate into certain parameters. The 
following diagram indicates the location of the 
information and the parameters which should 
be entered.

Hints and Tips

The direction of rotation of the motor can be 
reversed during commissioning by changing 
over two of the output connections on the 
inverter, or by pressing the Forward/Reverse 
button.

Parameters 

P000 

to 

P009

 can always be 

read or set.  Access to all other parameters is 
controlled by the contents of 

P009

. The 

factory default value is '0' which only allows 
access to 

P000 

to 

P009

. Changing its value

to ‘3' allows all parameters to be accessed 
permanently. See Operator Manual for the 
function of other values of 

P009

.

In case there are problems with the
parameter settings and you wish to start 
again, change 

P944

 to '1'. This will reset to 

the default settings.

The value displayed in 

P000 

is the output

frequency of the inverter, this is the default 
setting but it can be changed by altering the 
value in 

P001

. For example, changing 

P001 

to a value of '5' will cause the inverter to 
display the RPM of the motor in 

P000

. See 

the Operator Manual for other settings of 

P001

.

The default value (0) of parameter 

P006

 

ensures that the drive runs at the frequency 
set in 

P005

. In order to control the output 

frequency by an analogue input signal, the 
value of 

P006

 should be set to '1'. For other 

methods of control using 

P006

, see the 

Operator Manual.

DIP selection switches are used to select a 
range of 0-10V or 0-20mA for the 
analogue input. See the Operator Manual for 
more information.

An 

F002

 fault is often caused by either too 

short a ramp time or too much voltage boost. 
An increase  in the values in 

P002 

will 

increase the ramp time. Alternatively lower 
the values in 

P078

 and 

P079

 to reduce the 

voltage boost. Please note that if 

P078

 falls 

below '100' (default value for MMV) then the 
motor may under-perform at low frequencies.

An 

F001

 fault is often caused by attempting

to stop the motor too quickly - increasing the 
value in 

P003

 (ramp-down time) will reduce 

this possibility.

If the display flashes during operation, the 
drive is registering a warning. Check 

P931

 

for the cause.
