Par. Description
P-31 Keypad Start Mode Select
This parameter is active only when operating in Keypad Control Mode (P-12 = 1 or 2) or Modbus Mode (P-12 = 3 or 4). When settings
0 or 1 are used, the Keypad Start and Stop keys are active, and control terminals 1 and 2 must be linked together. Settings 2 and 3
allow the drive to be started from the control terminals directly, and the keypad Start and Stop keys are ignored.
0 : Minimum Speed, Keypad Start
1 : Previous Speed, Keypad Start
2 : Minimum Speed, Terminal Enable
3 : Previous Speed, Terminal Enable
5 : Preset Speed 4, Keypad Start
6 : Current Speed, Terminal Start
7 : Preset Speed 4, Terminal Start
P-32 Index 1 : Duration
Index 2 : DC Injection Mode
Index 1: Defines the time for which a DC current is injected into the motor. DC Injection current level may be adjusted in P-59.
Index 2 : Configures the DC Injection Function as follows :-
0 : DC Injection on Stop. DC is injected into the motor at the current level set in P-59 following a stop command, after the output
frequency has reduced to P-58 for the time set in Index 1.
Note If the drive is in Standby Mode prior to disable, the DC injection is disabled
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 : 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 : Disabled
1 : Enabled With Software Protection. Enables the internal brake chopper 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
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
Index 1 : Address
Index 2 : Baud Rate
Index 3 : Communication loss protection
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.
3 Index : Watchdog Timeout : Defines the time for which the drive will operate without receiving a valid command telegram to
rd
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-37 Access Code Definition
Defines the access code which must be entered in P-14 to access parameters above P-14
P-38 Parameter Access Lock
0 : Unlocked. All parameters can be accessed and changed
1 : Locked. Parameter values can be displayed, but cannot be changed except P-38.
P-39 Analog Input 1 Offset
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
