10.3 Operation of synchronous-gearless motors with DSV 544*-Lift
10.3.1 Synchronous winches with absolute encoder SSI option or second encoder ATB
It is imperative that the motor phases DSV5445 output terminals U1 - U2 - U3 be
connected one-to-one to the motor terminals, e.g. 1 – 2 – 3.
A check of the rotating field is not sufficient for synchronous motors.
The interpretation of the direction terminal for UP and DOWN can be set only by means
of the variable E0C “Rotation direction”.
The rotary encoder cable may not be removed with the converter switched ON. If this is
nevertheless done, a reset must be activated at the DSV so that the initialisation of the
rotor position is restarted.
The "SSI, EnDat ®” option card or “2
nd
ATB encoder” and the "internal UD cable" are
required.
Jumper "JP3" is always on "1Vpp" and the pulses per revolution in cell 0E4A to "2048".
The DSV 5445 Lift for synchronous gearless (with SSI option or 2
nd
ATB encoder) is
always preset to suit the winch type; i.e. before commissioning, you check or change
only the speed, the lift suspension and the driving wheel diameter of the lift, after a test
run the “direction of rotation” 0E0C (up and down signal) and in case for having an
ACP/DCP option card in use set input E8 to 24V.
Changing the suspension 0E40 from 2:1 to 1:1; i.e. 2 times the value of 0E18 and 0E22.
Changing the suspension 0E40 from 1:1 to 2:1; i.e. 0.5 times the value of 0E18 and
0E22 (0E18 “Return Ramp B”, 0E22 “Run-up ramp HL”)
The parameters / variables F0, F1, F2, F30, F31, t, E4A, E52, E54 E58, E5A, E5E,
E60, E6E must not be arbitrarily. Unexpected behaviour of the drive can otherwise
occur.
10.3.2 Lift programs for synchronous gearless winches
Due to the growing number of gearless drives, separate files are available for the individual types which are
configured to suit the motor data, encoder and activation type (*7TZ, resp. ACP/DCP option card).
Visit our old website www.dietz-electronic.de/gearlist.htm to get the list of all actual command
programs and updates *.KOM, *.UPD including synchronous gearless drives (or on the ’CD’)!
10.3.3 First initialisation, allocation of absolute value encoder and rotor
Synchronous motors require correct allocation of the absolute value encoder and rotor (RHO).
The DSV 5445 supplies DC current during the first initialisation. The magnetic field generated by it draws the
rotor into an exactly defined position that the absolute value encoder detects and which is stored as an offset
in the variable 0E6E “RHO”.
Synchronous gearless Winches with SSI or EnDat ® encoder (option SSI) can be adjusted by the winch
manufacturer in that way, that the winch is working immediately by using our factory setting RHO=0 in
variable 0E6E. Additional the winch manufacturer can specify a value for variable 0E6E "RHO-0", that
has to be set before primary initialisation.
Synchronous gearless winches with 8-channel encoder (option second encoder ATB-type), or other
encoder systems, always require the primary initialisation (except value is written on motor type plate).
After removing or readjusting the encoder system, you always have to do the primary initialisation. In that
case ropes and load should be not on the winch, brakes must be opened and contactors must be closed.
