Overview
NOTE
Please refer to the Sinus Penta’s
Installation Instructions Manual
for the description of the
serial links and connections.
NOTE
For a greater immunity against communication interference, an optional optoisolated serial
board (ES822) may be used instead of RS485 serial link. Serial links RS232 and RS485 can
interface with ES822 board.
Please refer to the Sinus Penta’s
Installation Instructions Manual
for the description of the
optional optoisolated board.
NOTE
The parameters described in this menu are
Rxxx
parameters.
Once changed and saved, they become active only when the drive is next switched on or
when the control board is reset (by holding down the
RESET
key for more than 5 secs).
Drives of the SINUS PENTA series may be connected to peripheral devices through a serial link. This enables both
reading and writing of all parameters normally accessed through the display/keypad. Two-wire RS485 is used, which
ensures better immunity against disturbance even on long cable paths, thus reducing the communication errors.
Two serial links are available.
Serial Link 0
is provided with a 9-pole, male D connector;
Serial Link 1
is provided with
an
RJ45 connector (or a three-phone connector) connected to the display/keypad.
NOTE
The display/keypad connected through RJ45 connector dialogues correctly with the drive
using the default values preset in the parameter set for serial link 1.
The drive will typically behave as a slave device (i.e. it only answers to queries sent by another device). A master
device (typically a computer) is then needed to start serial communications.
The following items may be configured for both serial links:
1. The drive MODBUS address.
2. The drive response delay to a Master query.
3. The baud rate of the serial link (expressed in bits per second);
4. The time added to the 4 byte–time;
5. The serial link watchdog (which is active if the relevant parameter is not set at 0);
6. The type of parity used for serial communications.

The Watchdog alarms determined by the serial link may be the following:
A061
Serial alarm n.0 WDG
A062
Serial alarm n.1 WDG
A081
Keypad Watchdog
The first two alarms trip when no legal message is sent from the serial link to the drive for a time longer than the time
set in the relevant watchdog parameters;
these alarms
are active only if parameters R005 or R012 are set other
than zero.
The third alarm trips only if the
display/keypad used as a reference/command source
detects a communication loss
for a time longer than 2 seconds.
