New ”Heavy Duty” and “Normal Duty” ratings for the F7
The Drive’s capacity is categorized on two types of load characteristics, Heavy Duty and Normal Duty. The table below
explains which drive selections apply to each duty and the features provided with the selected duty. Parameter C6-01 affects
the drives carrier frequency setting, and in some models, the 100% output current rating. The carrier frequency setting can
change the overload capacity and maximum output frequency.
C6-01 Setting Carrier Frequency Output Current Ratings
Overload
Capacity Maximum Output
Frequency
0: Heavy Duty
(F7 default) Low (2kHz) Level A
(Matches HD
3 nameplate rating)
150% 300 Hz
2: Normal Duty
Higher than Heavy Duty
(Adjustable lower only)
(Varies by model) Level B > A
(On some models, see table)
(Matches ND 3 nameplate rating)
Varies by model
(See Appendix 1) 400 Hz
Product C6-01 Heavy/Normal Duty Setting
New F7 C6-01 Drive Duty Selection Setting
0: Heavy Duty (default)
• Rated output current is HD (Heavy Duty) rating on drive nameplate.
• Overload Capacity is 150% for 1 min.
• Carrier frequency is fixed l at 2kHz
• Maximum output frequency is 300Hz.
• L8-15: OL2 Characteristic selection@low speed (=0 Disabled) - allows 150% for 1 minute at any
frequency.
2: Normal Duty 2
• Output current is ND (Normal Duty) rating on drive nameplate.
• Overload capacity varies by model. (See appendix 1)
• Setting C6-02 Carrier Frequency greater than default is prohibited. (Default is highest possible setting)
• Maximum output frequency is 400Hz.
• Fixed low speed protection method: Carrier is automatically lowered when output frequency is < 6.0 Hz
and current is >100%.
• L8-15: OL2 Characteristic selection@low speed (=1 Enabled) expedites OL2 at low output frequencies-
6 Hz and below.
GPD515/G5 Similar to (Normal Duty ) but with 150% OL
• Singular output current value on nameplate.
• Overload capacity is 150% for 1 min.
• Full range carrier adjustment C6-02
(Drive must be derated when carrier is set above default, software protected by OL2)
• Maximum output frequency is 400Hz.
• L8-15: Characteristic selection@low speed (=1 Enabled) expedites OL2

Technical manual and promotional material will only refer to Normal Duty and Heavy Duty. The term Normal
Duty refers to Normal Duty 2 (C6-01=2) setting.
