03 PARITY BITS:
[*1 (1,3)] This menu item defines the parity used for the Modbus communications.
1=Parity Off / 2=Odd Parity/ 3=Even Parity
04 BITS
: [*1(1,2)] It defines the bits for the Modbus. 1=7 / 2=8
05 DRIVER
[*2 (1,2)] DO NOT CHANGE THIS PARAMETER
06 FREEZE REMOTE SETPOINT:
[TRUE or *FALSE] This menu item, when set to TRUE, freezes the
remote speed set point when communications are lost. If this value is set to FALSE, the remote set point
goes to 0 when communications are lost.
07 FREEZE INITIAL BSLD REF:
[TRUE or *FALSE] This menu item, when set to TRUE, freezes the
initial baseload set point when communications are lost. If this value is set to FALSE, the initial Modbus
baseload set point goes to 0 when communications are lost. This is applicable if the control mode is
Local.
08 FREEZE BSLD REF:
[TRUE or *FALSE] This menu item, when set to TRUE, freezes the remote
baseload set point when communications are lost. If this value is set to FALSE, the remote baseload set
point goes to 0 when communications are lost.
09 FREEZE LEVEL REF:
[TRUE or *FALSE] This menu item, when set to TRUE, freezes the remote
level set point when communications are lost. If this value is set to FALSE, the remote level set point
goes to 0 when communications are lost.
10 FREEZE STROKE ACTUATOR:
[TRUE or *FALSE] This menu item, when set to TRUE, freezes the
actuator stroke value when communications are lost. If this value is set to FALSE, the remote level set
point goes to 0 when communications are lost.
11 FREEZE BSLD REF - REM:
[TRUE or *FALSE] This menu item, when set to TRUE, freezes the
remote baseload set point when communications are lost. If this value is set to FALSE, the remote
baseload set point goes to 0 when communications are lost. This is applicable if the control mode is
Remote.
12 CHOOSE MODBUS COMM:
[TRUE or *FALSE] This menu item, when set to TRUE, enables the
Modbus communication on the RS-232 port. This will deactivate the Servlink communication.
26 SYNCHRONIZE
01 SPEED BIAS:
[MONITOR] This menu item displays the Synchronizer/Load Control bias value.
02 SPEED BIAS ANALOG GAIN:
[*1 (0.001,100)] This menu item defines the Synchronizer/Load Control
bias gain. This number is multiplied by the Speed Bias signal.
03 SPD BIAS AN SIG FILTR TC:
[*0.01 (0.001,3)] This menu item defines the time constant for the Lag
Tau filter for the Speed Bias Control signal. When this value is left at 0.01, the lag filter is basically turned
off. This value should be left at 0.01 unless noise is present on the speed bias signal.
04 SPEED BIAS DIGITAL RATE:
[*0.1 (0.01,1)] This is the rate (%/s) at which the speed bias raises or
lowers the speed of the 2301E-HT when digital inputs are used as the speed bias (Speed Bias Raise and
Speed Bias Lower).
27 CONFIG SPD SW
If any relay output is configured as a speed switch, then the speed switches are configured here. If no
relay outputs are configured as speed switches, then this menu does not affect the control and can be
skipped.
If any relay output is configured as a speed switch, then the speed switches are configured here. If no
relay outputs are configured as speed switches, then this menu does not affect the control and can be
skipped.
01 SW1 - DECREASING?:
[TRUE or *FALSE] This determines if Speed Switch #1 is an increasing
switch or a decreasing switch. If the switch should trigger when the unit is slowing down, then this value
should be set to TRUE. If the switch should trigger when the unit is speeding up, then this value should
be set to FALSE.
02 SPD SW1 - HI SET:
[*100.0 (0.0,200.0)] This is the high % of rated set point for the speed switch.
When the switch is increasing, this set point is the trip point of the speed switch. When the switch is
decreasing, this set point is the reset point of the speed switch.
03 SPD SW1 - HI DELAY:
[*0.0 (0.0, 600.0)] This is the time (in seconds) that the speed should be
greater than HI SET to energize the relay when configured to Increasing or to de-energize the relay when
configured to decreasing.
