1
Traction max current defined by a two minute S2-2 min test with 100% current loading applied.
2
Traction 1-hr rating is by a S2-60 min rating.
3
Controller Lifetime Rating calculated @ 60% traction modulation depth.
4
The isolated CAN option applies to both CAN ports. Each isolated port is without internal 120-Ω termination.
5
The -101 models include CAN isolation and the Inertia Measurement Unit (IMU).
PWM operating frequency: 10 kHz.
Maximum encoder frequency: 30 kHz. (see Chapter 2 for higher encoder frequency values)
Maximum controller output frequency: 599 Hz.
Electrical isolation to heatsink: 500 Vac (minimum).
Power Terminals: 5 (B+, B–, U, V, W).
Logic Connector Pin Count: 23 or 35 (controller basis).
Logic Connector Current Rating: 8A per pin (Maximum).
KSI Inrush Current: ≤ 10A, Max ≤ 2ms overall, with an initial peak duration ≤ 20 μs, at room temperature.
Precharge Current: 2A for < 1 sec (typical).
Storage ambient temperature range: –40°C to 95°C (–40°F to 203°F).
Operating ambient temperature range: –40°C to 50°C (–40°F to 122°F).
Internal heatsink operating temp. range: –40°C to 95°C (–40°F to 203°F).
Maximum Operating Altitude: 3,000 meters ( 9842.5 feet)
Package environmental rating: IP65 per IEC60529.
Note: Compliance requires AMPSEAL 23 or 35-pin receptacle [plug] connector with all
wire silos sealed.
Thermal cutback: Controller linearly reduces maximum current limit with an internal heatsink
temperature from 85°C (185°F) to 95°C (203°F); complete cutoff occurs above 95°C
(203°F) and below –40°C (–40°F).
Design life: F2-A 24V = 8,000 hours
F2-A 48V 150A = 8,000 hours
F2-A 48V 240A = 2,000 hours
F4-A and F6-A = 20,000 hours
Operating duration at max. current: All current ratings are rms values per motor phase. S2–60 minute current is the typical
current achievable before thermal cutback occurs, with an ambient temperature of
25°C and the controller mounted to a 6 mm thick vertical steel plate with 6 km/h (1.7
m/s) airow perpendicular to the plate.
