Magnetek Quattro DC Elevator Drive Benutzerhandbuch

−  Open F1 and F2 and ensure control power 

brought into fuse F1 and F2 is 230VAC! 

IMPORTANT:  Double-check all the power 
wires and motor wires to make sure that they 
are securely tightened down to their respective 
lugs (loose wire connections may cause 
problems at any time). 

1.  Encoder   

a. Encoder 

isolation 

−  The encoder must be electrically 

isolated from the motor frame and 
the motor shaft. 

b. Encoder 

cable 

−  The cable type should PVC braided 

shielded type with three 22ga 
twisted pairs.  A and A/, B and B/, 
common and V should be the 
signals paired together.   

−  The encoder shield is not to be 

connected at the encoder end.  On 
the drive side of the cable a portion 
of PVC material 1inch [25mm] 
should be removed approximately 
12inches [300mm] from the 
connection to the customer 
interface PCB (A6) to expose the 
shield material.  This point is 
required to be secured under a 
clamp located under the control 
tray.   Do not connect the shield to 
any other point.  Refer to the EMC 
Compliance on page 97. 

2. Motor 

frame 

a.  The motor frame is required to be 

grounded.  The bond wire should be 
returned to the common ground point 
located in the Quattro enclosure (PE). 

3.  Three phase power  

a.  The three phase wires must be run 

with a ground wire.  This ground wire, 
which is connected back to the utility 
ground, is required to be connected to 
the Quattro ground (PE). 

4.  Control power, 230VAC 

a.  The neutral side of the control power is 

required to be grounded at the Quattro 
ground (PE). 

Encoder Set-up 
Electrical interference and mechanical speed 
modulations are common problems that can 
result in improper speed feedback getting to 
the drive.  To help avoid these common 

problems, the following electrical and 
mechanical considerations are suggested. 

IMPORTANT 
Proper encoder speed feedback is essential 
for a drive to provide proper motor control. 

Electrical Requirements: 

−  Insulate both the encoder case and shaft 

from the motor 

−  Incremental encoder type 

−  Use twisted pair cable with shield tied to 

chassis ground at drive end 

−  Use limited slew rate differential line 

drivers 

−  Do not allow capacitors from internal 

encoder electronics to case 

−  Do not exceed the operating specification 

of the encoder/drive (300Khz @ rated 
motor speed maximum) 

−  Use the proper encoder supply voltage 

and use the highest possible voltage 
available. The Quattro DC provides both 
5VDC and 12VDC.  Magnetek 
recommends using the 12VDC for the 
encoder supply. 

Mechanical Considerations: 

−  Use direct motor mounting without 

couplings 

−  Use hub or hollow shaft encoder with 

concentric motor stub shaft 

−  If possible, use a mechanical protective 

cover for exposed encoders 

−  It is not advisable to use friction wheels 

Enter / Verify the encoder pulses entered in 
the ENCODER PULSES (A1) parameter 
matches the encoder’s nameplate.  

Motor Parameter Set-up 
Enter / Verify the following from the motor’s 
nameplate: 
1.  Motor Current (RATED MTR CURRENT 

(A6)) 

2.  Motor Voltage (RATED ARM VOLTS (A6)) 
3.  Motor field amps, forcing (FULL FLD 

AMPS (A6)) 

4.  Motor field amps, running (WEAK FLD 

AMPS (A6)) 

5.  Motor field amps, standing (STNDBY 

FIELD (A6)) 

Hoist way Parameter Set-up 
Enter / Verify the hoist way parameters: 
1.  CONTRACT CAR SPD (A1) parameter 

programs the elevator contract speed in 
ft/min or m/s.
