P1.18
Up/Down Percentage
Range:
0.0 to 100.0 %
Default:
Read Only
Displays the value of the Up/Down reference as a percentage which can be increased or decreased by the keypad or drive terminals. This
parameter is unidirectional with motor direction set by the configured run forward or run reverse commands, see
Run/Stop Configuration
(P6.13).
The value can be used for speed control by selecting Keypad (5) or Terminal Up/Down (6) in
Frequency Reference Configuration
(P2.03) or in to
Frequency Reference 1 Selector
(P2.21) to
Frequency Reference 4 Selector
(P2.24). When selected for speed control, 100 % is the
Maximum
Frequency Limit
(P2.02).
See
Up/Down Percent Configuration
(P2.14) and
Up/Down Percentage Time to Max
(P2.15) for information on Up/Down control configuration.
When controlled by the drive terminals this feature is sometimes referred to as a Motorized Potentiometer.
P1.19
PID Output Percentage
Range:
± 100.00 %
Default:
Read Only
Displays the percentage output for the PID controller. This includes the feed forward term selected by
PID Feed Forward Selector
(P5.05).
The value can be used for speed control by selecting a PID configuration in
Frequency Reference Configuration
(P2.03) or in
Frequency
Reference 1 Selector
(P2.21) to
Frequency Reference 4 Selector
(P2.24). When selected for speed control, 100 % is the
Maximum Frequency
Limit
(P2.02).

Default:
Read Only
Displays a set of indicators that represent the status of the PID and threshold detector.
If a function has been selected in
PID Enable Selector
(P5.11) it must be active to enable the PID controller. If an input has been configured as the
PID Hardware Enable
(13), this must also be active to enable the PID controller.
P1.21
PID Error
Range:
± 100.00 %
Default:
Read Only
Displays the PID Error. This is the difference between the PID reference and PID feedback which are selected by
PID Reference Selector
(P5.03)
and
PID Feedback Selector
(P5.04).
P1.22
Motor Thermal Percentage
Range:
0 to 100 %
Default:
Read Only
Displays an estimate of the motor temperature as a percentage of the maximum allowed temperature for the motor. This estimation allows a longer
overload period when the motor is cool and reduces the allowable period as the motor reaches its maximum temperature. The period depends on
the output current and the estimated motor starting temperature.
The action taken by the drive can be set in
Thermal Protection Action
(P3.21).
If
Thermal Protection Action
(P3.21) is set to Limit, the output current will be limited if this parameter reaches 100 %, and the limit will then be
removed once this parameter drops below 95 %.
If
Thermal Protection Action
(P3.21) is set to Error, the error will occur when this parameter reaches 100 %.
An alarm is indicated if this percentage is larger than 75 % and the current magnitude is such that it is still increasing, see
Alarm Indicators
(P1.09).
P1.23
Drive Thermal Percentage
Range:
0 to 100 %
Default:
Read Only
Displays the internal temperature of the drive which will change depending on the output current. This is displayed as a percentage of the
maximum allowed drive temperature.
The action taken by the drive can be set in
Thermal Protection Action
(P3.21).
If
Thermal Protection Action
(P3.21) is set to Limit, the output current will be limited if this parameter > 90 %.
If
Thermal Protection Action
(P3.21) is set to Error, the error will occur when this parameter = 100 %.
An alarm is indicated if this percentage is > 95 % and cleared when < 75 %, see
Alarm Indicators
(P1.09).
Bit
Indicator
Description
Bit
0
PID Enabled
Indicates the PID is enabled and active.
Bit
1
PID Limit Applied
Indicates that the PID output is being limited by
PID Output Lower Limit
(P5.09) or
PID Output
Upper Limit
(P5.10), or a limit following the addition of the Feed Forward is being applied.
Bit
2
Threshold Detector Output
Indicates that the threshold detector output is active.
