No.
Set up overload protection circuits when running multiple motors from a single drive.
16
Note:
Verify that ground wiring for models UUoEoooo and UUoWoooo is correct before turning on the EMC filter
17
switch.
18 Verify phase advancing capacitors, input noise filters, or GFCIs are NOT installed on the output side of the drive.
Properly wire the power lines to terminals X, Y, and Z of drive models 4o0720 to 4o0930, and terminals X, Y, and Z of
19
the harmonic filter module.
Properly wire the power lines to terminals X1, Y1, and Z1 of drive models 4o0720 to 4o0930, and terminals X1, Y1,
20
and Z1 of the harmonic filter module.
Properly wire the power lines to terminals p2 and n2 of mdrive models 4o0720 to 4o0930, and terminals p2 and n2 of
21
the harmonic filter module.
22 The cable between drive models 4o0720 to 4o0930 and harmonic filter module should not exceed 5 m (16.4 ft.).
The resistance value between the terminals R/L1, S/L2, and T/L3 of the harmonic filter module should exceed 1000 Ω
23 when connected to drive models 4o0720 to 4o0930. If the resistance value does not exceed 1000 Ω, check for main circuit
wiring mistakes between the harmonic filter module and drive models 4o0720 to 4o0930.
24 Use twisted-pair line for all drive control circuit wiring.
25 Ground the shields of shielded wiring to the GND
26 For 3-Wire sequence, set parameters for multi-function contact input terminals S1 – S8, and wire control circuits.
27 Properly wire any option cards.
28 Check for any other wiring mistakes. Only use a multimeter to check wiring.
29 Properly fasten drive control circuit terminal screws.
30 Pick up all wire clippings.
31 Ensure that no frayed wires on the terminal block are touching other terminals or connections.
32 Properly separate control circuit wiring and main circuit wiring.
33 Analog signal line wiring should not exceed 50 m (164 ft.).
34 Safe Disable input wiring should not exceed 30 m (98.5 ft.).
35 Verify the logic of Safety Monitor Output Signal (DM+, DM-).
Disconnect the internal EMC filter by moving the SW screw to the OFF position for floating, impedance grounded, or
36
asymmetrically grounded networks.
Properly wire the control signal lines to Module Communications Connector port CN500 of drive models 4o0720 to
37
4o0930, and Module Communications Connector port CN500 of the harmonic filter module.
38 The cable between drive models 4o0720 to 4o0930 and harmonic filter module should not exceed 5 m (16.4 ft.).
