Disabling the LOCAL/REMOTE Key (o2-01)
Set o2-01 to 0 to disable the LOCAL/REMOTE Key on the Digital Operator.
If the key is disabled, it cannot be used anymore to switch over the frequency reference source or the RUN
command source between LOCAL and REMOTE.
Disabling the STOP Key (o2-02)
This parameter is used to set whether the STOP key on the operator is active during remote control (b1-02 ≠ 0)
or not.
If o2-02 is set to 1, a STOP command from the operators STOP key will be accepted. If o2-02 is set to 0 it will
be disregarded.
Initializing Changed Parameter Values (o2-03)
You can save the current Inverter parameter setting values as user-set parameter initial values. Therefore
parameter o2-03 has to be set to 1.
To initialize the Inverter parameters using the user-set initial values in memory set parameter A1-03 to 1110.
To clear the user-set initial values in memory, set o2-03 to 2.
Setting the Frequency Reference using the UP and DOWN Keys without Using the
Enter Key (o2-05)
This function is active when frequency references are input from the Digital Operator. When o2-05 is set to 1,
you can increment and decrement the frequency reference using the UP and DOWN keys without using the
Enter key.
Operation Selection when the Digital Operator is Disconnected (o2-06)
This function selects the operation when the digital operator gets disconnected when a RUN command is
active.
If o2-06 is set to 0 the operation is continued.
If o2-06 is set to 1 the output is switched off and the motor coasts to stop. The fault contact is operated. When
the operator is reconnected an OPR (Operator disconnected) is shown.
Cumulative Operation Time (o2-07 and o2-08)
The inverter has a function that counts the operation time of the inverter cumulatively.
Using parameter o2-07 the cumulative operation time can be changed, e.g. after a replacement of the control
board. If parameter o2-08 is set to 0 the inverter counts the time whenever the power supply is switched ON.
If o2-08 is set to 1 the time when a RUN command is active is counted only. The factory setting is 0.
Cooling Fan Operation Time (o2-10)
This function counts the operating time of the inverter mounted fan cumulatively.
Using parameter o2-10 the counter can be reset, e.g. when the fan was replaced.
Fault Trace Initialize (o2-12)
This function can be used to initialize the fault trace by setting parameter o2-12 to 1.
