TR150 and TR170
Function:
Enter the low frequency limit
corresponding to the low motor shaft
speed (that is low reference value) in
parameter 5-52 Term. 29 Low Ref./Feedb.
Value. See Illustration 3.9.
Function:
Enter the high frequency limit
corresponding to the high motor shaft
speed (that is high reference value) in
parameter 5-53 Term. 29 High Ref./Feedb.
Value.
Function:
Enter the low reference value limit for the
motor shaft speed [RPM]. This is also the lowest
feedback value. Set terminal 29 to digital input
(parameter 5-13 Terminal 29 Digital Input =
applicable value).
Function:
Enter the high reference value [RPM] for
the motor shaft speed and the high
feedback value. Select terminal 29 as a
digital input (parameter 5-13 Terminal 29
Digital Input = applicable value).
Function:
controlled digital outputs and relays.
A logical 1 indicates that the output is
high or active.
A logical 0 indicates that the output is
low or inactive.
