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.

0 : Disabled
1: Enabled With Software Protection
. Brake chopper enabled with software protection for a 200W continuous rated resistor
2: Enabled Without Software Protection
. Enables the internal brake chopper 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
setpoint, 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
setpoint, 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.

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 ‘
’ suffix selects trip on loss of communication. An ‘
’ suffix
means that the drive will coast stop (output immediately disabled) but will not trip.

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(%) - P-39) x P-35)

-
Allows the user to program the TECDrive 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
1
0
-
0: Direct Operation
. Use this mode if when the feedback signal drops, the motor speed should increase.
1: Inverse Operation
. Use this mode if when the feedback signal drops, the motor speed should decrease.
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%

Selects the source for the PID Reference / Setpoint
0: Digital Preset Setpoint
. P-45 is used
1: Analog Input 1 Setpoint
. Analog input 1 signal level, readable in P00-01 is used for the setpoint.
