10.2.1.3 Hardware connection to EPM ECD synchronous lift motor (resolver):
Attention: The power connection "U, V, W" must be connected exactly in this sequence to the terminals "U1,
U2, U3". Both the phase sequence and also the rotating field are important in this case.
The 12-pole round connector to the resolver has the following pins assignment, whereby differentiation is
made between "standard and AES versions".
Name 12pole-IP65-Pin 15pole-SUB-D-Pin (option card)
S1/cos 1 7 COS (+)
S3/cos-low 2 8 COS\(-)
S2/sin 3 5 SIN (+)
S4/sin-low 4 6 SIN\(-)
R1/Ref 7 1 OSC (+)
R2/Ref-low 8 2 OSC\(-)
Screen 9 12 Screen
The following pins are assigned as follows for the standard version:
Thermistor 5 23 thermistor connector on DSV
Thermistor 6 24 thermistor connector on DSV
The following pins are assigned as follows for the AES version:
HS U 5 to AES auxiliary controller
HS V 6 to AES auxiliary controller
HS W 10 to AES auxiliary controller
GND 11 to AES auxiliary controller
+UB 12 to AES auxiliary controller
A pre-formed resolver cable of 6 m length can be obtained under order no. 9544R812.
10.2.2 First initialisation of EPM / ECD with resolver interface
The resolver for the EPM / ECD winches are matched mechanically to the angular displacement angle RHO
= 0 in the factory. A first initialisation must be performed after dismantling (e.g. resolver exchange),
misalignment (e.g. loose screw connection) or lack of factory adjustment.
You require a PC/laptop with EmoSoftLift and the interface cable to perform the first
initialisation.
Please execute the following steps carefully. The first initialisation should be performed only by
experienced users, who have read and understood this chapter.
You require a clamp-on ammeter and/or PC/laptop with EmoSoftLift and interface cable to
check that you have found the “correct" RHO at the correct motor phase. To do this, it must be
possible to run the synchronous motor in both directions at no load and at medium speed.
A defective first initialisation means that you must remove the cables again and repeat all steps
once more.
