Code Name
5201
STATION NUMBER
Sets the slave number for the ACS 160 in Modbus network.
Range: 1 - 247
Note! Modifications take effect only on the next power up.
5202
COMM SPEED
Defines the communication speed of the ACS 160 in bits per second
(bps).
Note! Modifications take effect only on the next power-up.
5203
PARITY
Defines the parity to be used in Modbus communication. Parameter also
defines the number of stop bits. In Modbus communication, the number
of stop bits is 2 with no parity bit, and 1 with even or odd parity.
0 =
NONE
1 = EVEN
2 = ODD
Note! Modifications take effect only on the next power-up.
5204
COMM FAULT TIME
Time limit for communication loss detection. This parameter is used
together with parameter 5205
COMM FAULT FUNC to define the ACS 160
operation when the communication with the master device in the Modbus
network is lost.
The master device in the Modbus network must signal its presence to
every slave device (ACS 160) in the network by periodically writing
Command Word, External Reference 1 or External Reference 2 to each
ACS 160 in the network. Maximum write period is set by this parameter.
Range: 0.1 - 60.0 s
Note! During the first 4 seconds after power-up, communication fault is
not evaluated to compensate for possible long system start-up delay.
3 = 300 bps 48 = 4800 bps
6 = 600 bps 96 = 9600 bps
12 = 1200 bps 192 = 19200 bps
24 = 2400 bps
