52.1. Overview
NOTE
See the OPTIONAL BOARDS FOR FIELDBUS section in the Sinus Penta’s
Motor Drives
Accessories – User Manual for the description of the optional board required.
NOTE
The parameters included in this menu are Rxxx parameters.
Once saved, they are 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).
CAUTION
This menu is not applicable to ES919 communications boards (see relevant section in
the Sinus Penta’s Motor Drives Accessories – User Manual
). ES919 boards act as
gateways and change the MODBUS
RS485 packets into the packets of each protocol
being used.
The exchanged parameters are all the Mxxx
measures from the Sinus Penta to the
Master and all the Ixxx
inputs from the Master to the Sinus Penta (as detailed in the
MEASURES MENU, Table 89 and Table 91).
52.1.1. ALARM A070 (COMMUNICATION SUSPENDED)
Alarm A070 trips if the Sinus Penta is not sent any legal message via FIELDBUS within the timeout set in parameter
R016. Set parameter R016 = 0 to disable alarm A070.
A legal message is as follows:
- PROFIdrive: The master drive writes bit 11=1 of the Control Word (see PROFIdrive COMMUNICATIONS
BOARD – Installation and Programming Guide).
- Other Fieldbuses: The master drive writes the digital input word (word 5 - M035) with bit 15=1 or as set in
parameter R018b.
A legal message is the word of the digital inputs (M035) with bit 15=1 written by the master.
Important: this is enabled only when the drive receives the first message with this bit =1.
Do the following to reset alarm A070:
- restore communication between the Master drive and the Sinus Penta;
- Re-activate the control of bit 15 of the digital input word as above (bit 11 of the Control Word when using
PROFIdrive);
- Send a reset command to the board.
If communications between the Master and the Slave (Penta) cannot be restored, alarm A070 is reset after setting
parameter R016 to zero and after resetting the Penta drive. When the drive is next powered on, resetting the alarm
reset will affect the drive control board.
NOTE
Alarm A070 does not trip if, due to the parameters in the CONTROL METHOD MENU or due
to the status of the SOURCE SELECTION or LOC/REM inputs (see
DIGITAL INPUTS
MENU
), the information sent via serial link is not currently used for the commands or the
references.
