10 YASKAWA TOEPC71061752B GA500 Drive Installation & Primary Operation
Item Specification
Altitude
1000 m (3281 ft) Maximum
Note:
Derate the output current by 1% for each 100 m (328 ft) to install the drive in altitudes between
1000 m to 4000 m (3281 ft 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 m to 4000 m (6562 ft to 13123 ft) and grounding the neutral
point on the power supply.
Contact Yaskawa or your nearest sales representative when not grounding the neutral point.

Table 3.3 Protection Functions
Item Specification
Motor Protection
Electronic thermal overload protection
Momentary
Overcurrent
Protection
Drive stops when the output current is more than 200% of the HD output current.
Overload
Protection
Drive stops when the output current is more than these overload tolerances:
• HD: 150% of the rated output current for 60 seconds.
• ND: 110% of the rated output current for 60 seconds.
Note:
If output frequency < 6 Hz, the drive can trigger the overload protection function when the output
current is in the overload tolerance range.
Overvoltage
Protection
200 V class: Stops when the DC bus voltage is more than approximately 410 V
400 V class: Stops when the DC bus voltage is more than approximately 820 V
Undervoltage
Protection
Single-phase 200 V class: Stops when the DC bus voltage decreases to less than approximately 160 V
Three-phase 200 V class: Stops when the DC bus voltage decreases to less than approximately 190 V
Three-phase 400 V class: Stops when the DC bus voltage decreases to less than approximately 380 V
