Multi-function Digital Inputs (H1-01 to H1-05)
nSetting Precautions
• When both external search commands 1 and 2 are set for the multi-function contact terminals, an OPE03
(invalid multi-function input selection) operation error may occur. Set either external search command 1 or
external search command 2.
• If speed search during startup is selected when using V/f control with PG, the Unit will start from the fre-
quency detected by PG.
• If performing speed search using external search commands, add an external sequence so that the period
when the run command and external search command are both ON is at the very least the Minimum Base-
block Time (L2-03).
• If the Inverter output is equipped with a contact, set the contact operation delay time in the Speed Search
Wait Time (b3-05). The factory setting is 0.2 s. When not using the contact, you can reduce the search time
by making the setting 0.0 s. After waiting for the speed search wait time, the Inverter starts the speed
search.
• Parameter b3-02 is a current detection speed search (current detection level for search completion). When
the current falls below the detection level, the speed search is viewed as completed, and the motor acceler-
ates or decelerates to the set frequency. If the motor cannot restart, lower the set value.
• If an overcurrent (OC) is detected when using speed search after recovery following a power loss, lengthen
the Minimum Baseblock Time (L2-03).
nApplication Precautions for Speed Searches Using Estimated Speed
• When using V/f control with or without a PG, always perform stationary autotuning for only line-to-line
resistance before using speed searches based on estimated speeds.
• When using open loop vector control, always perform rotational autotuning before using speed searches
based on estimated speeds.
• If the cable length between the motor and Inverter is changed after autotuning has been performed, per-
form stationary autotuning for only line-to-line resistance again.

resistance is performed.
