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.

The isolated CAN option applies to both CAN ports. Each isolated port is without internal 120-Ω termination.
PWM operating frequency: 10 kHz.
Maximum encoder frequency: 30 kHz.
Maximum controller output frequency: 500 Hz.
Electrical isolation to heatsink: 500 Vac (minimum).
Power Terminals: 5 (B+, B-, U, V, W).
Logic Connector Pin Count: 35.
Logic Connector Current Rating: 8A per pin (Maximum).
KSI Inrush Current: ≤ 10A, Max ≤ 2ms overall, with initial peak ≤ 20 us, 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).
Package environmental rating: IP65 per IEC60529.
Note: Compliance requires AMPSEAL 23-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: 20,000 hours.
Operating duration at max. current: 2 minutes minimum, with initial temperature of 25°C and no additional external
heatsink.
Weight: 1.9 kg (4.4 lbs.).
Dimensions, WxLxH: 180 x 140 x 75 mm (7.08 x 5.5 x 2.6 inches).
Baseplate material: Aluminum.
Baseplate:
(bottom surface)
Roughness grade of N8 (ISO 1302), with a atness tolerance of 0.3mm.
Mounting holes: 4x Ø7mm
