Par. Description Minimum Maximum Default Units
1 : DC Injection on Start. DC is injected into the motor at the current level set in P-59 for the time set in Index 1 immediately after
the drive is enabled, prior to the output frequency ramping up. The output stage remains active during this phase. This can be used
to ensure the motor is at standstill prior to starting.
2 : DC Injection on Start & Stop. DC injection applied as both settings 0 and 1 above.
P-33 Spin Start 0 2 0 -
0 : Disabled
1 : Enabled. When enabled, on start up the drive will attempt to determine if the motor is already rotating, and will begin to control
the motor from its current speed. A short delay may be observed when starting motors which are not turning.
2 : Enabled on Trip, Brown Out or Coast Stop. Spin start is only activated following the events listed, otherwise it is disabled.
P-34 Brake Chopper Enable (Not Size 1) 0 4 0 -
0 : Disabled
1 : Enabled With Software Protection. Brake chopper enabled with software protection for a 200W continuous rated resistor
2 : Enabled Without Software Protection. Brake chopper enabled without software protection. An external thermal protection
device should be fitted.
3 : Enabled With Software Protection. As setting 1, however the Brake Chopper is only enabled during a change of the frequency
set point, and is disabled during constant speed operation.
4 : Enabled Without Software Protection. As setting 2, however the Brake Chopper is only enabled during a change of the
frequency set point, and is disabled during constant speed operation.
P-35 Analog Input 1 Scaling / Slave Speed Scaling 0.0 2000.0 100.0 %
Analog Input 1 Scaling. The analog input signal level is multiplied by this factor, e.g. if P-16 is set for a 0 – 10V signal , and the scaling
factor is set to 200.0%, a 5 volt input will result in the drive running at maximum frequency / speed (P-01)
Slave Speed Scaling. When operating in Slave Mode (P-12 = 9), the operating speed of the drive will be the Master speed multiplied
by this factor, limited by the minimum and maximum speeds.
P-36 Serial Communications Configuration See Below
Index 1 : Address 0 63 1 -
Index 2 : Baud Rate 9.6 1000 115.2 kbps
Index 3 : Communication loss protection 0 3000 t 3000 ms
This parameter has three sub settings used to configure the Modbus RTU Serial Communications. The Sub Parameters are:
1st Index : Drive Address : Range : 0 – 63, default : 1
2
nd
Index : Baud Rate & Network type : Selects the baud rate and network type for the internal RS485 communication port.
For Modbus RTU : Baud rates 9.6, 19.2, 38.4, 57.6, 115.2 kbps are available.
For CAN Open : Baud rates 125, 250, 500 & 1000 kbps are available.

rd
Index : Watchdog Timeout : Defines the time for which the drive will operate without receiving a valid command telegram to
Register 1 (Drive Control Word) after the drive has been enabled. Setting 0 disables the Watchdog timer. Setting a value of 30, 100,
1000, or 3000 defines the time limit in milliseconds for operation. A ‘t
tt
t’ suffix selects trip on loss of communication. An ‘r
rr
r’ suffix
means that the drive will coast stop (output immediately disabled) but will not trip.
P-37 Access Code Definition 0 9999 101 -
Defines the access code which must be entered in P-14 to access parameters above P-14
P-38 Parameter Access Lock 0 1 0 -
0 : Unlocked. All parameters can be accessed and changed
1 : Locked. Parameter values can be displayed, but cannot be changed
P-39 Analog Input 1 Offset -500.0 500.0 0.0 %
Sets an offset, as a percentage of the full scale range of the input, which is applied to the analog input signal. This parameter
operates in conjunction with P-35, and the resultant value can be displayed in P00-01.
The resultant value is defined as a percentage, according to the following :- P00-01 = (Applied Signal Level(%) x P-35) - P-39
P-40 Index 1 : Display Scaling Factor 0 16.000 0.000 -
Index 2 : Display Scaling Source 0.000 3 0 -
Allows the user to program the BFI to display an alternative output unit scaled from either output frequency (Hz), Motor Speed
(RPM) or the signal level of PI feedback when operating in PI Mode.
Index 1 :Used to set the scaling multiplier. The chosen source value is multiplied by this factor.
Index 2 : Defines the scaling source as follows :-
0 : Motor Speed. Scaling is applied to the output frequency if P-10 = 0, or motor RPM if P-10 > 0.
1 : Motor Current. Scaling is applied to the motor current value (Amps)
2 : Analog Input 2 Signal Level. Scaling is applied to analog input 2 signal level, internally represented as 0 – 100.0%
3 : PI Feedback. Scaling is applied to the PI feedback selected by P-46, internally represented as 0 – 100.0%
P-41 PI Controller Proportional Gain 0.0 30.0 1.0 -
PI Controller Proportional Gain. Higher values provide a greater change in the drive output frequency in response to small changes
in the feedback signal. Too high a value can cause instability
P-42 PI Controller Integral Time 0.0 30.0 1.0 s
PI Controller Integral Time. Larger values provide a more damped response for systems where the overall process responds slowly
P-43 PI Controller Operating Mode 0 3 0 -
0 : Direct Operation. Use this mode if an increase in the motor speed should result in an increase in the feedback signal
1 : Inverse Operation. Use this mode if an increase in the motor speed should result in a decrease in the feedback signal
2: Direct Operation, Wake at Full Speed. As setting 0, but on restart from Standby, PI Output is set to 100%
3: Reverse Operation, Wake at Full Speed. As setting 0, but on restart from Standby, PI Output is set to 100%
