4-6 ACS/ACH 400 Direct N2 Bus Interface
9 Protocol Software Error
This parameter shows the protocol software
error code.
The possible codes are:
0 = NO FAULT
1 = NO ADDRESS
N2 node address of the drive has to be set and
the drive has to be powered down and back up
for the setting to take effect.
2 = TIME-OUT FAULT
Communication time-out time has elapsed.
3 = LINE BREAK
This error may occur if the RS485 wires are
swapped.
Output Point
Configuration
The N2 Bus implementation follows the normal
control place logic configuration on the ACS/
ACH 400 drive. This will mean that to use
output points to control the drive, the drive must
also be configured to receive commands from a
Communication port.
Before any control commands can be given
through the direct N2 connection, parameter
5006 COMM COMMANDS value must be set to
OEM APPLIC (3).
Required setups for each individual point are
listed below.
