P-30
Terminal Mode Restart function
N/A
N/A
Auto-0
-
Defines the behaviour of the drive relating to the enable digital input and also configures the Automatic Restart function.
: Following Power on or reset, the drive will not start if Digital Input 1 remains closed. The Input must be closed after a
power on or reset to start the drive.
: Following a Power On or Reset, the drive will automatically start if Digital Input 1 is closed.
to
: Following a trip, the drive will make up to 5 attempts to restart at 20 second intervals. The drive must be
powered down to reset the counter
.
The numbers of restart attempts are counted, and if the drive fails to start on the final attempt,
the drive will fault with, and will require the user to manually reset the fault.
P-31
Keypad / Modbus Mode Restart Function
0
3
1
-
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.
Settings 0 and 2 : The drive will always start at the Minimum Frequency / Speed (P-02)
Settings 1 and 3 : The drive will always start at the last operating Frequency / Speed
0 : Minimum Speed, Keypad Start
1 : Previous Speed, Keypad Start
2 : Minimum Speed, Terminal Enable
3 : Previous Speed, Terminal Enable
P-32
DC Injection Time On Stop
0.0
25.0
0.0
s
Defines the time for which a DC current is injected into the motor once the output frequency reaches 0.0Hz. The voltage level is the
same as the boost level set in P-11.
P-33
Spin Start (S2 & S3 Only) / DC Injection Time On Start (S1 Only)
0
1
0
-
Frame Size 2 and 3 Drives only – 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.
Frame Size 1 Drives Only – DC Injection Time On Starting
Sets a time for which DC current is injected into the motor to ensure it is stopped when the drive is enabled.
P-34
Brake Chopper Enable
0
2
0
-
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.
P-35
Analog Input 1 Scaling
0.0
500.0
100.0
%
Scales the analog input 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)
P-36
Serial Communications Configuration
See Below
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
2
nd
Index : Protocol & Baud Rate
: Setting
(factory default setting) disables Modbus communications, and allows the
Optistick to be used with the drive. Selecting a baud rate between 9.6kbps to 115.2kbps allows Modbus communication, but
disables the operation of the Optistick.
3
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-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
P-40
Display Speed Scaling Factor
0.000
6.000
0.000
-
Allows the user to program the Optidrive to display an alternative output unit scaled from the output frequency or speed, e.g. to
display conveyer speed in metres per second. This function is disabled if P-40 = 0.00
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 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
