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).

Motor Protection: L1-01 and L1-02
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.

E2-01
Motor Rated Current
Sets the motor nameplate full load current in amperes (A). This set value becomes
the reference value for motor protection, torque limit, and torque control. This
value is automatically set during Auto-Tuning.

Less than 11 kW: 2 digits below the decimal
point, 11 kW or more: 1 digit below the
decimal point.

Current
Sets the motor 2 name plate full load current in amperes (A). This set value
becomes the reference value for motor protection, torque limit, and torque
control. This value is automatically set during Auto-Tuning.

Use L1-13 (Continuous Electrothermal Operation Selection) to select whether
electronic thermal value is “held” or “not held” when the power supply is
turned off.
When connecting several motors to one drive, set “0” (disabled) and install a
thermal relay on each motor.
