Drive Status Monitors: U1-01 To U4-13 - YASKAWA CIMR-JC4A0002BAA Quick Start Manual

4.5 Basic Operation
• Disable motor protection (L1-01 = 1) when running multiple motors from the same drive.
Attach a thermal relay for each motor to provide overload protection.
• Use L1-13 (Continuous Electrothermal Operation Selection) to select whether the
electrothermal value is "held" or "not held" when power supply is turned off. Default setting
is 1 (Enabled).
• In the case of a general purpose (standard) motor, the cooling capability is reduced at a low
speed. Motor overload protection (oL1) may occur in frequencies lower than motor rated
current. Use an exclusive-use or inverter-duty motor to operate the drive at rated current at
low frequency.
