Appendix
DCP 4 Setup and Calibration
The commissioning and setup of the
HPV900S2 in DCP 4 mode is relatively simple,
all that is required is the calibration of the drive
to ensure the actual elevator speed exactly
matches our commanded speed
– this is
essential for accurate leveling accuracy and
good performance
Activating DCP4
To activate DCP4 simply navigate to SERIAL
MODE (C1) parameter and change to DCP4.
Note
: The control system need to have the
ability to operate in DCP4 mode and must also
have the relevant settings enabled.
Equalizing speeds
Once the elevator is traveling at contract
speed and all learn runs have been completed
the calibration can take place.
In the HPV900S2, navigate to the CONTRACT
CAR SPEED (A1) parameter and make a note
of the speed entered (this should be the same
as the V4 speed in the A3 menu of the drive).
Next navigate to the CONTRACT MOTOR
SPEED (A1) parameter and make a note of
the value also.
Next you need to run the elevator and
accurately monitor the speed at which the
elevator is traveling, this is usually possible
within the control system however if required
the speed of the elevator could be monitored
with a hand tachometer.
Take the elevator to the top floor and then run
it to the bottom floor at high speed, make a
note of the speed displayed whilst the elevator
is traveling record the actual speed the
elevator is traveling at (either from within the
control systems processor or my manually
monitoring it).
If this speed is not exactly the same as the
speed displayed in the CONTRACT CAR
SPEED, use the previously noted data in to the
following formula:
It is then recommended to repeat the process
to verify the actual speed now accurately
reflects the commanded speed. If it matches
then the process is complete, if not restart the
process
