1.
Select H4-02 or H4-03 by pressing the
and
keys.
2.
Press the
key while the drive is stopped and the following
voltage is output for adjustment:
Output voltage = (10 V x Output Gain (H4-02) + Output Bias (H4-03).
Using this output, adjust output gain (H4-02) and output bias (H4-03).

This section explains how to set motor overload protection.

Electronic Thermal Motor Protection
The drive has built-in electronic thermal overload protection to detect overload conditions.
This protection meets standards set by UL and cUL for motor thermal overload protection.
The protective feature is activated when the output current rises above the motor rated current
for a specified time. This speed sensitive protective feature interrupts the motor current to
protect the motor wiring and windings in the event of overload, eliminating the need for an
external overload device. When multiple motors are used with a single drive, separate overload
devices are required to properly protect the individual motor branches.
