When this function is enabled, the drive will start to run and sit at four points of the configured speed range to measure the actual
currents. If there is insufficient power available from the array to run at the highest speeds, the drive will trip on Atf-03 to indicate that the
measurements could not be made. Disable the load monitoring function and repeat the exercise when there is enough power available
from the array.
P8-07
Motor Current Monitoring Bandwidth

A
This parameter sets a bandwidth around the load profile generated by P8-06. If P8-06 has been set to an appropriate value to detect
an over/under load condition and the drive operates outside of the bandwidth set in P8-07 for a period longer than that set in P8-08
then the drive will detect the over/under load condition. The value entered in P8-07 is the value between the ‘normal’ current and the
over/under load condition hence the total bandwidth is 2 x P8-07.

This parameter sets a bandwidth around the load profile generated by P8-06. If P8-06 has been set to an appropriate value to detect
an over/under load condition and the drive operates outside of the bandwidth set in P8-07 for a period longer than that set in P8-08
then the drive will detect the over/under load condition. The value entered in P8-07 is the value between the ‘normal’ current and the
over/under load condition hence the total bandwidth is 2 x P8-07.

Low Power Restart Delay

0
s
This parameter can be used to limit the drive from starting and stopping the pump repeatedly after collapsing the array at times of very low
irradiance when the drive is used in PID mode for pressure regulation. This function is disabled when the parameter is set to 0s. The function
works by entering a ‘Low Power Standby’ mode if the array voltage (DC Bus voltage) drops below the value set in P8-18 and will sit in
this state and not attempt a restart until the time set in this parameter has elapsed.
When in this Standby mode, the LED display will indicate
oP
and the OLED/TFT display will indicate Low Power Standby.
Bit 15 in the status word will go high to indicate that this mode is active.

Standby Mode

-
This parameter selects the operation of the standby mode in conjunction with the time set in P2-27.
P8-14 = 0 – Standby based on the operating speed of the motor with the level set in P3-14.
P8-14 = 1 – Standby based on the PID feedback value with the standby and wake-up levels being set in P8-15 and P8-16.
P8-14 = 2 – Standby based on the level of AI 1 with standby and wake-up levels being set in P8-15 and P8-16.
P8-14 = 3 – Standby based on DC Bus voltage level with standby and wake-up levels being set in P8-15 and P8-16.
P8-15
Standby Activation Level
0.0

0.0
%
Specifies the level for activation of the standby function.
If P8-14 = 1:
When the PID is operated in direct mode (P3-04 = 0), if the level of the PID feedback is higher than this level the drive will enter in
Standby mode after the time set in P2-27. The delay timer will be reset to 0 if the feedback goes below this level before entering
standby mode. When the PID is operated in inverse mode (P3-04 = 1), if the level of the PID feedback is lower than this level the drive
will enter in Standby mode after the time set in P2-27. The delay timer will be reset to 0 if the feedback goes above this level before
entering standby mode.
If P8-14 = 2:
If the level of analogue input 1 is lower than this level the drive will enter in standby mode after the time set in P2-27. The delay timer will
be reset to 0 if the value of analogue input 1 goes above this level before entering into standby mode.
If P2-27 is 0, the drive will never enter standby mode.
If P8-14 = 3:
If the level of the DC Bus Voltage is Lower than this level the drive will enter in Standby mode after the time set in P2-27. The delay timer
will be reset to 0 if the DC Bus Voltage lifts above this level before entering standby mode.
