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,
the selected frequency reference can be incremented and decremented the UP and DOWN keys without using
the Enter key. The function work only if parameter b1-01 is set to 0.
Operation Selection when the Digital Operator/LED Monitor is Disconnected (o2-06)
This function selects the operation when the digital operator/LED Monitor 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 accumulated operation time can be changed, e.g. after a replacement of the control
board. If parameter o2-08 is set to 0, the inverter accumulates 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 has been replaced.
Fault Trace Initialize (o2-12)
This function can be used to initialize the fault trace by setting parameter o2-12 to 1.
“Number of Travels” counter Initialize (o2-15)
Using this parameter the lift operation counter monitor (U1-55) can be initialized.
 Copying Parameters (JVOP-160-OY only)
The following three digital operator functions can be used in order to copy/verify parameter settings:
• Store Inverter parameter set values in the Digital Operator by setting o3-01 to 1 (READ)
• Write parameter set values stored in the Digital Operator to the Inverter by setting o3-01 to 2 (COPY)
• Compare parameter set values stored in the Digital Operator with Inverter parameters settings by setting
o3-01 to 3 (VERIFY)
The data saved in the operator can be protected from overwriting by setting parameter o3-02 to 0. In this case
a READ command can not be executed. If it is nevertheless still done, “PrE” will be displayed at the operator.
