. If you switch the frequency reference and operation command input between
communication RS-485 and control terminals, please set the following parameters:
a. 00-05=1 (control terminal AI1 or AI2 as a reference frequency)
b. 00-02=1 (control terminal S1 or S2 as an operation command)
c. set from 03-02 to 03-07(Set 03-02 to 03-07 (one of multi-function digital input
terminals S1 to S8 is set to 28 (Operation selection of remote mode).
(27). Inverter overheating warning (setting = 31).
. When the inverter detects a overheat signal, the digital operator will display a
warning message of "OH2", but the inverter goes on operating. When the inverter
overheating warning is removed, the digital operator will automatically resume to the
original display. You do not need to press the RESET key.
(28). Sync command (setting = 32)
This function is for switching the serial pulse input and the frequency reference
converted from other frequency reference (based on 00-05 setting).
When you select Local / Remote mode control selection (setting is 25) or the
Remote mode (setting is 26), and the corresponding input is opened, this function is
invalid.
. Only in the stop status of the inverter, you can set/clear sync command.
. For the sync operation, refer to page. 4-79.
(29). DC braking (setting = 33).
When stopping the inverter, you can use this setting to execute DC braking
function through the set terminals.
If you input the operation command or jog command, DC braking operation will be
cleared and the motor will start running.
Refer to the DC braking time diagram in the following Figure 4.3.24.
