10.7 Drive Derating
YASKAWA SIEPC71061753C GA500 Technical Manual 343
Note:
The setting range changes when the L8-35 [Installation Method Selection] value changes:
• 0 [IP20/UL Open Type]: -10 °C to +60 °C
• 1 [Side-by-Side Mounting]: -10 °C to +50 °C
• 2 [IP20/UL Type 1]: -10 °C to +50 °C
• 3 [External Heatsink/Finless]: -10 °C to +50 °C
The drive automatically adjusts the drive rated current to the best value as specified by the set temperature. Set the
ambient temperature of the area where you install the drive to a value that is more than the drive rating.
Refer to Derating Depending on Ambient Temperature on page 342 for information about derating as specified by
ambient temperature.

Note:
• Parameter A1-03 [Initialize Parameters] does not initialize this parameter.
• This parameter is set to the correct value when the drive is shipped. Change the value only in these conditions:
–Side-by-Side installation
–When you install a UL Type 1 kit on an IP20/UL Open Type drive to convert the drive to an IP20/UL Type 1 drive.
–Mounting a standard drive with the heatsink outside the enclosure panel.
• Do not change the settings for finless-type drives.
The drive automatically adjusts the overload protection detection level to the best value for each setting value.
Refer to Derating Depending on Ambient Temperature on page 342 for information about derating as specified by
ambient temperature.
0 : IP20/UL Open Type
Use this setting to install IP20/UL Open Type drives.
Make sure that there is 30 mm (1.18 in) minimum of space between drives or between the drive and side of the
enclosure panel.
1 : Side-by-Side Mounting
Use this setting to install more than one drive side-by-side.
Note:
You cannot install finless-type drives side-by-side.
2 : IP20/UL Type1
Use this setting to install IP20/UL Type 1 drives.
Note:
You cannot install an IP20/UL Type 1 Kit (optional) on a finless-type drive.
3 : External Heatsink/Finless
Use this setting when the heatsink (cooling fin) is outside the enclosure panel or when you install a finless-type
drive.
◆ Altitude Derating
Install the drive in a location that has an altitude of 1000 m (3281 ft) or lower.
Derate the output current by 1% for each 100 m (328 ft) to install the drive in altitudes between 1000 to 4000 m
(3281 to 13123 ft).
It is not necessary to derate the rated voltage in these conditions:
• Installing the drive at 2000 m (6562 ft) or lower
• Installing the drive between 2000 to 4000 m (6562 to 13123 ft) and grounding the neutral point on the power
supply.
If you do not ground the drive with a neutral network, contact Yaskawa or your nearest sales representative.
