05 1=ASCII / 2=RTU RS-232:
[*2 (1,2)] This integer selects the format of the communication. If the value
is tuned to 1, the Modbus will communicate in ASCII format. If the value is tuned to 2, the Modbus will
communicate in RTU (Remote Terminal Unit) format.
06 TIMEOUT (sec) RS-232:
[*10 (0.5,30)] This value is the number of seconds the 2301E-HT will wait
before it results in an Exception or Link Error.
10 CONFIG SYNC_LOAD CONTROL
This menu needs to be configured if a speed bias bias signal is going to be used in the control.
01 SYNCHRONIZE ONLY?:
[TRUE or *FALSE] If the Synchronizer/Load Control is only going to be used
to synchronize the unit, then this value should be set to TRUE.
02 SIG TYPE
– 2=AN / 3=DIG:
[*1 (1,3)] If the speed bias signal source is coming from an analog input
this variable must be configured to 2. In this case an analog input must be configured as a speed bias
input. If the speed bias signal source is coming from digital inputs this variable must be configured to 3. In
this case two digital inputs must be configured, one for speed bias raise and another for speed bias lower.
A value 1 says that neither analog nor digital inputs are going to be programmed for speed bias function.
