‹ New “Heavy Duty” and “Normal Duty” Ratings for the A1000
The drive’s capacity is rated for two types of load characteristics, Heavy Duty (HD) and Normal Duty (ND). The table
below explains the drive characteristics for HD and ND ratings. Parameter C6-01 affects the drives carrier frequency
setting, and in certain models, the value of 100 % output current rating is also affected.

C6-01 Setting Carrier Frequency Output Current Ratings Overload Capacity Maximum Output Frequency
0: Heavy Duty
2 kHz (default)
Can be increased w/o derate
(Refer to Appendix 1)
HD nameplate rating 150 % 400 Hz
1: Normal Duty
(A1000 default)

Product C6-01 Heavy/Normal Duty Setting
New A1000
C6-01 Drive Duty Selection Setting
0: Heavy Duty
• Rated output current is the HD (Heavy Duty) rating on drive nameplate.
• Overload capacity is 150 % for 1 minute.
• Carrier frequency is defaulted to 2 kHz but can be increased to 8 kHz or 5 kHz w/o derating on certain models (Refer to Appendix 1)
• Carrier frequency is automatically reduced when:
• output frequency is < 6.0 Hz and current is >100 %
• output frequency is > 6.0 Hz and current is > 112 %
• Maximum output frequency is 400 Hz (except on larger models)
• L8-15: OL2 Characteristic selection@low speed (=1 Enabled) expedites OL2 at low output frequencies below 6 Hz.
1: Normal Duty (default)
• Output current is ND (Normal Duty) rating on drive nameplate.
• Overload capacity is 120 % for 1 minute.
• Carrier frequency is defaulted to Swing PWM (2kHz) but can be increased with derating on most models (Refer to Appendix 1)
• Carrier is automatically reduced when:
• output frequency is < 6.0 Hz and current is >100 %
• output frequency is > 6.0 Hz and current is > 112 %
• Maximum output frequency is 400 Hz (except on certain larger models)
• L8-15: OL2 Characteristic selection@low speed (=1 Enabled) expedites OL2 at low output frequencies below 6 Hz.
GPD515/G5
Similar to Normal Duty, but with 150 % OL
• Singular output current value on nameplate.
• Overload capacity is 150 % for 1 minute.
• Full range carrier adjustment C6-02.
• Drive must be derated when carrier is set above default, software protected by OL2.
• Maximum output frequency is 400 Hz.
• L8-15: Characteristic selection @ low speed (=1 Enabled) expedites OL2.
