L1-02: Motor Overload Protection Time
Setting Range: 0.1 to 5.0 min
Factory Default: 1.0 min
Parameter L1-02 determines how long the motor is allowed to operate before the oL1 fault occurs when the drive is
running at 60 Hz and at 150% of the full load amp rating (E2-01/E5-03) of the motor. Adjusting the value of L1-02 can
shift the set of oL1 curves up the y axis of the diagram below, but will not change the shape of the curves.

‹ Precautionary Notes on External Heatsink (IP00/Open Type Enclosure)
An external attachment can be used to project the heatsink outside of an enclosure to ensure that there is sufficient air
circulation around the heatsink. When using an external heatsink, UL compliance requires covering exposed capacitors in
the main circuit to prevent injury to surrounding personnel. Contact a Yaskawa sales representative or Yaskawa directly
for more information on this attachment.
‹ Safe Disable Input Function
This section explains the Safe Disable function and how to use it in an elevator installation. Contact Yaskawa if more
information is required.
„ Specifications
The Safe Disable inputs provide a stop function in compliance with “Safe Torque Off” as defined in the IEC61800-5-2.
Safe Disable inputs have been designed to meet the requirements of the ISO13849-1, Cat. 3 PLd and IEC61508, SIL2.
A Safe Disable Status Monitor for error detection in the safety circuit is also provided.
Inputs / Outputs
Two Safe Disable inputs and one EDM output according to ISO13849-1 Cat.3 PLd,
IEC61508 SIL2.
Operation Time Time from input open to drive output stop is less than 1 ms.
Failure Probability
Demand Rate Low PFD = 5.15E -5
Demand Rate High or
Continuous
PFH = 1.2E -9
Performance Level
The Safe Disable inputs satisfy all requirements of Performance Level (PL) d according to
ISO13849-1 (DC from EDM considered).
