114 Unidrive SP Regen Installation Guide
www.controltechniques.com Issue Number: 2
The powered-up clock always starts at zero each time the drive is powered-up. The time can be changed by the user from the keypad, serial comms
or an application module. If the data is not written with the various parts in the correct range (i.e. minutes are greater than 59, etc.) the clock is set to
zero on the next minute. This clock may be used for time stamping the trip log if Pr 6.28 = 0.
The run time clock increments when the drive inverter is active to indicate the number of minutes that the drive has been running since leaving the
Control Techniques factory. This clock may be used for time stamping the trip log if Pr 6.28 = 1.
Pr 6.24 and Pr 6.25 form the energy meter that indicates energy supplied to/from the drive in kWh. For motor control modes a positive value indicates
net transfer of energy from the drive to the motor. For regen mode a positive value indicates a net transfer of energy from the supply to the drive. The
energy meter is reset and held at zero when Pr 6.17 is one.
Instantaneous read out of the cost/hour of running the drive. This requires Pr 6.16 to be set up correctly.
