Use With Mein Series Inverter - Nice NDCC4001 Instrucciones Y Advertencias Para La Instalación Y El Uso

CAUTION! – The learning phases must never be interrupted. If this oc-
curs, the entire learning procedure must be repeated. At the end of the
learning phase, if LEDs "L3" and "L4" flash, this means that there is an
error. The position recognition procedure can be repeated at any time
also after the installation.

3.17 - Programming unit Oview
The use of the programming unit Oview enables complete and rapid management
of installation, maintenance and troubleshooting of any malfunctions of the
whole automation system.
Oview can be connected to the control unit by means of the BusT4 connector
on the control unit.
To access the BusT4 connector, open the box and insert the connector in its
seat (fig. 21).
In general, Oview can be positioned at a maximum distance of 100 m of cable
from the control unit; it can be connected to multiple control units simultaneously
(max. 16) and can also remain connected during normal operation of the
automation.
To operate with Oview, it is very important to observe the warnings in the Oview
instruction manual and Oview System Book system manual.
If an OXI type radio receiver is present in the control unit, Oview enables access
to the parameters of the transmitters memorised in this receiver. For detailed
information, refer to the instruction manual of the Oview programmer or the
control unit function datasheet also available on the website www.niceforyou.com

3.18 - Use with MEIN series inverter

The NDCC2301 control unit can pilot gearmotors with a MEIN series inverter
on board. The use of the inverter improves the motor's performance: controlling
the speed, accelerations/decelerations and the torque; in addition, its use is
recommended for High-speed doors.
There are two ranges of Nice gearmotors with preassembled inverter of the
MEIN series:
- HDFI, HDFNI for High-speed doors
- SDI, SDNI for sectional doors
The control unit supplies the mono-phase 230 Vac 50/60 Hz voltage to the
inverter and the commands are transmitted via an RS485 industrial interface.
Having completed the connections as described in the motor's instruction man-
ual, the inverter is ready to be installed:
1 Memory deletion for sectional or High-speed doors (paragraph 5.3.1);
2 Activate inverter function (L7, level 1);
3 Recognition of the connected devices (see paragraph 3.12);
4 Recognition of limit positions on opening and closing with the use of MEIN
family inverter (paragraph 3.15).
The standard values are set in the factory. These may be changed via the Oview
programmer or by programing with the keys of the board.
The parameters which may be shown / changed are:
• Speed when opening
• Speed in opening deceleration
• Speed when closing
• Speed in closing deceleration
• Minimum frequency
• Acceleration
• Deceleration
• Emergency deceleration
• Start-up
• Motor warm up
• Alarm and protection management
• Inverter status
For the specifications of the values of each parameter, please consult the func-
tion datasheet for industrial control units at www.niceforyou.com
