Drive Status Monitors: U1-01 To U6-19; Drive Status Monitors - YASKAWA V1000 Series Installation & Start-Up Manual

4.6 Basic Drive Setup Adjustments
• 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.
