(1) Refer to the PLC module manual.
(2) Refer to the Anybus-CC communication manual.
(3) Refer to the programming manual.
(4) Use DB-9 pin, male-to-female, straight-through cable (serial mouse extension type) for connecting the keypad to the inverter or Null-Modem standard
cable. Maximum cable length: 10 m (33 ft).
Examples:
- Mouse extension cable - 1.80 m (6 ft); Manufacturer: Clone.
- Belkin pro series DB9 serial extension cable 5 m (17 ft); Manufacturer: Belkin.
- Cables Unlimited PCM195006 cable, 6 ft DB9 m/f; Manufacturer: Cables Unlimited.
(5) Inverters with serial number below 1011361739 use MMF-01 control card.
(6) The MMF-03 module has a reserved space for the user (for example: write the application software version SoftPLC).
7.2.1 Use of External Dynamic Braking Module DBW03 and DBW04
The braking module can be added externally to any model, and especially to the models of frame sizes F, G
and H, which do not feature built-in braking IGBT.
This module is connected to the DC link terminals and the braking resistor must be connected to the braking
module terminals.
See electrical diagram example for the frame sizes F, G and H in
Figure 3.9 on page 3-19
and
Figure 3.10
on page 3-20
.
See also DBW03 and DBW04 instructions manual for detailed information.
For frame sizes F and G it's recommended to use DBW03 model.
For frame size H it's recommended to use DBW04 model.
NOTE!
Dynamic braking in models from frame sizes F, G and H:
- For accessing the DC link connections it's necessary to remove top cover. See
Figure 3.13 on
page 3-24
.
- The maximum rms braking currents on DC link terminals of standard models in frame sizes F, G
and H are the following:
Frame size F: 143 Amps-rms
Frame size G: 216 Amps-rms
Frame size H: rated DC current according
