>> L7Z DIFFERENCE WITH FV


MAIN DIFFERENCE WITH FV/G5


New Static Autotune modes


Reduced size and reduced price


Improved performance (enhanced algorythms like DC braking, new functions)


New generation IGBTs. Lower voltage drop (reduced losses), smaller size.


Fan silent control when not working.


New DCCT current sensors. Faster response (1V/
µs, FV was 8
V/
µs). Linearity


New generation capacitors with higher ripple current capacity, smaller size.


Better error handling and detection (GF is detected by specific slow circuitry (300
µs
, OC is detected faster from the new DCCT in 8
µs
)


Same nominal rating as FV, although reduced duty cycle.


No RS
-
422 available in L7Z. RS
-
232 MEMOBUS is available.


Full 4 line LCD display


Of course : MANY NEW LIFT SOFTWARE FUNCTIONS

SPEED SELECTION (I)


THE SPEED PRIORITIES AND FV COMPATIBILITY MODE


The L7Z provides several sequence behaviour selection to allow FV update, old 2
speed systems update, new multispeed systems, etc… with minimum wiring.


Unfortunately, in FV compatibility mode some special functions related with the
levelling speed selection are not possible in firmware 1030 (as the inverter is not
aware of which is the levelling speed) : Short floor, feedforward slip, feedforward
DC injection, etc.


TO GET MAXIMUM BENEFIT FROM Firmware 1030 use D1
-
18=1 or 2 !!


Also they provide increased sequence safety

NEW LIFT SEQUENCE FAULT MESSAGES


SE1 : Contactor feedback fault. If multifunction is set to 86 (Output Contactor
feedback), then SE1 might appear :


CASE 1: Output contactor of output inverter kept closing before contactor closed
command set.


CASE 2: Output contactor cannot be closed within the contactor close delay time.


CASE 3 :Output contactor is opened during inverter running.


SE2 : On brake release, the inverter checks if the motor current is higher than
25% of No
-
Load current. If not SE2 error is generated



SE3 : During RUN, the inverter checks if motor current is higher than 25% of
No
-
Load current. If not, SE3 error is generated.

current (VF) or torque reference (OLV). This will be applied during levelling.

the inverter starts, the inverter accelerates to S1

SHORTFLOOR OPERATION


L7Z calculates estimated area (distance) from Vn to Vl with current parameters.


When levelling command is received, if actual speed is below 40% of Vn then the inverter
keeps 40% reference for a calculated time to achieve the estimated area and reduce
levelling time.
