Disabling the LOCAL/REMOTE Key (o2-01)
Set o2-01 to 0 to disable the LOCAL/REMOTE Key on the LED or LCD 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 Digital Operator and the settings in b1-01 and b1-02.
Disabling the STOP Key (o2-02)
This parameter is used to set whether the STOP key on the LED or LCD Digital 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, the Inverter will stop
according to the method set in parameter b1-03 (Stopping method). If o2-02 is set to 0 it will be disregarded.
Initializing Changed Parameter Values (o2-03)
The current Inverter parameter setting values can be saved as user-set parameter values. Therefore parameter
o2-03 has to be set to 1.
To initialize the Inverter parameters using the user-set initial values in memory parameter A1-03 has to be set
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 the frequency reference is input from any Digital Operator. When o2-05 is set to
1 and the frequency reference is input via any Digital Operator the reference can be incremented or decre-
mented using the UP and DOWN keys directly, pressing the ENTER button is not necessary.
Operation Selection when the Digital Operator is Disconnected (o2-06)
Parameter o2-06 selects whether a fault is detected when the Digital Operator is disconnected from the
Inverter.
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 relay is operated and the
Digital Operator Display shows an OPR fault when reconnected.
Cumulative Operation Time (o2-07 and o2-08)
The Inverter counts its operation time 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 1.
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. All previously stored
faults are deleted.
Energy Monitor Initialize (o2-14)
This function can be used to initialize the energy monitor by setting parameter o2-14 to 1.
