Motor Settings – Parameters 101-141
attention:
Are motor related parameters and are not normally changed.
group 2 – reference and limits.
Rotation Direction – Parameter 200
attention:
Sets rotation direction, normally set at 132 hz counter clockwise.
Minimum Output Frequency – Parameter 201
Minimum output frequency is normally set at 0 to 21 hz
dependant on the mode of operation.
Maximum Output Frequency – Parameter 202
Maximum output frequency is normally set at 50 hz. This figure
should not be exceeded as the inverter could be overloaded.
Reference Feedback – Parameter 203
Set to Min-Max and not normally changed.
Minimum Reference – Parameter 204
If operating in closed loop mode, set to minimum scale of the
feedback sensor, normally set to 0.0.
note:
Units of measurement are selected in parameter 416.
If operating in open loop mode, the units can only be displayed
as hz, normally set to minimum speed 0.0 hz.
Ramp Up/Down Times – Parameters 207, 208, 211, 212
Ramp up times normally set to 10 seconds.
attention:
Ramp down times normally set to 3 seconds. Longer times
should be used with higher kW motors.
Jog Frequency – Parameter 213
Normally set to 50 hz when the jog function is activated it will
override the normal reference input and run the pump at the
preset jog reference.
Reference Function – Parameter 214
Set to Sum. Not normally changed.
Preset Reference 1 – Parameter 215
(Set Point) if operating in closed loop mode, this parameter
should be set to the required set point as a percentage of the
maximum range of the feedback sensor. i.e. Sensor range 0 -4.0
Bar, set point required 2.0 Bar, parameter would be set to 50%. If
operating in open loop mode or sensorless mode this parameter
should be set to 0%.
Preset Reference 2 – Parameter 216
Set to 0% and not normally used.
Catch Up/Slow Down – Parameter 219
Set to 0% and not normally used.
Frequency Bypass Bandwidth – Parameter 229
If a skip frequency is entered at parameter 230 or 231 a %
bandwidth either side of these frequencies can be defined in
this parameter.
Frequency Bypass – Parameters 230-231
If resonance problems occur at particular frequencies, It is
possible to program two frequencies to be avoided.
group 3 – inputs and outputs.
Inputs and Outputs – Parameters 317-340
These parameters are not normally changed.
group 4 – special functions.
Special Functions – Parameters 400-446
These parameters are not normally changed.
group 5 – serial communications.
Bus Address – Parameter 500
This parameter allows specification of the address for each
inverter. Used in conjunction with plc/pc connection. Address
0 is used for the master unit, addresses 1-126 for slave units. A
repeater unit will be required if the total number of slave units
exceeds 30.
Baudrate – Parameter 501
Sets the speed of communication, set to a value that
corresponds with the transmission speed of the plc/pc.
Drive Control – Parameters 502-508
Allows control via terminal inputs and/or the Bus.
Bus Jog Frequency – Parameters 509-510
Activates the jog frequency via the Bus.
Protocol – Parameter 512
Selects the control word profile 0=Profidrive, 1=fc Drive.
Data Output – Parameters 513-635
Read only values of various functions.
