Electrical and Power Specifications
|Minimum power supply voltage||8 VDC|
Maximum absolute power supply voltage
60 VDC (continuous)
|Recommended power supply voltage|
12 VDC ~ 48 VDC
This voltage range ensures a safety margin including power supply tolerances and regulation during acceleration and braking.
|Internal drive DC bus capacitance|
Note that CAP-XCR uses ceramic capacitors. The capacitance value varies with DC bias and temperature.
|Logic power supply voltage (optional)|
8 to 50 VDC
Providing the logic supply is optional, as the drive is supplied from the DC bus (single supply) on its full operating voltage range. When supplied from logic, an intelligent switch will stop consuming from the DC bus.
|Boot-up time||4 s|
|Minimum shutdown time||500 ms|
Maximum continuous phase current
Typically, 10 A can be obtained working at 48 V, 50 kHz with an appropriate cooling to keep case temperature under 85 ºC. On higher temperatures an automatic current derating will be applied to protect the system. See Product Description#Thermal and Power Specifications below.
Maximum peak phase current
20 A @ 1 sec
Notice that peak current could be limited by an automatic current derating algorithm. In order to get 20 A, case temperature should be kept below 60 ºC.
|Maximum continuous switch-off rectified current|
Notice that maximum current is dependent on temperature and heatsink attached. At higher temperature, the lower the current. For more information about heatsink applied, see Product Description#Thermal and Power Specifications below.
A continuous use of disabled power stage as rectifier is not recommended for thermal limitations.

Thermal and Power Specifications
Standby power consumption
The following table shows the standby power consumption of the Capitan assuming 2 EtherCAT ports are active and communicating at full speed, no feedbacks or I/Os are connected. When the power stage is enabled, motor current is set to 0 and housing temperature is kept at 50 ºC.
|Power supply voltage||Typical total standby power consumption with single supply||Power savings by having dual supply with logic at 12 V*|
|Power stage disabled||Power stage enabled and switching at 0 current|
|EtherCAT (2 ports active)||CANopen||20 kHz||50 kHz||100 kHz||200 kHz|
|8 V||1.52 W||1.52 W||1.57 W||1.6 W||1.63 W||1.69 W||~0.0 W|
|12 V||1.54 W||1.54 W||1.6 W||1.63 W||1.68 W||1.78 W||~0.0 W|
|24 V||1.65 W||1.65 W||1.74 W||1.82 W||1.95 W||2.18 W||~0.08 W|
|48 V||1.90 W||1.92 W||2.10 W||2.31 W||2.65 W||3.32 W||~0.35 W|
|60 V||2.10 W||2.05 W||2.31 W||2.62 W||3.12 W||4.08 W||~0.45 W|
*If minimal standby power consumption is desired working at 24 V or higher it is suggested to have dual supply and provide 12 V or 24 V to the Logic. This reduces losses by allowing the main DC/DC converter to operate at peak efficiency.
The following diagram depicts the general dissipation model. The Capitan is designed to be mounted on a cooling plate or heatsink to achieve its maximum ratings. Please see Installation for more details. In order to calculate the heatsink requirements, the power dissipation can be estimated below.
In some low power applications, the Capitan is NOT required to be mounted to any heatsink. In this case its thermal resistance from housing/case to ambient Rth(h-a) can be estimated between 12 K/W, to 16 K/W assuming 10 cm clearance to allow air convection at sea level. For example, with the drive on standby at 1.65 W losses at 25 ºC air temperature the internal drive temperature can be 56 ºC. When the Capitan is not attached to a heatsink factors like air cooling, power cable thickness will have a significant effect on its temperature. Typically 2.2 W can be dissipated without heatsink, refer to the graph below to know which current can be handled.
*Product shown differ from Capitan XCR.
The following figure shows the maximum motor phase current at different case temperatures and operating points. The graph expresses the achievable current including the derating algorithm that limits the current based operation conditions and the power stage temperature.
Notice that current is expressed in crest value for a 3 phase BLAC motor. For further clarifications and conversion to equivalent RMS values please refer to Disambiguation on current values and naming for Ingenia Drives.
To ensure a proper performance of Capitan XCR, the case temperature should be held always below 85 ºC (Tc-max = 85 ºC).
Heat dissipation and heatsink calculation
The following figure shows the total power losses at different operating points. This includes logic supply and considers a single supply scenario. As can be seen, lower PWM frequency and voltage leads to lower power losses.
Please, use the following procedure to determine the required heatsink:
- Based on the voltage & continuous current required by your application and Power losses graph determine the generated Power Losses PL to be dissipated.
- For example: If the application requires 10 A @ 60 V (20 kHz) the PL will be 4.25 W
- Determine the Thermal impedance of the used thermal sheet Rth(c-h)
- For example, a thermal sheet TGX-150-150-0.5-0, which has an estimated thermal impedance of Rth(c-h) = 0.2 K/W
Based on the ambient temperature and using the following formula determine the maximum thermal impedance to air of the required heatsink Rth(h-a)
- For example: If the application requires 10 A @ 60 V (20 kHz) working at Ta = 25 ºC and we use a thermal sheet with Rth(c-h) = 0.2 K/W the required thermal impedance of the heatsink will be Rth(h-a) = 14.32 K/W
The following graph shows the electrical energy efficiency including logic for various operation points assuming 50 ºC case temperature and the drive delivering the maximum output power (i.e. maximum output voltage and motor speed). As seen, very high efficiencies > 99% can be achieved at 20 kHz PWM frequency.
Power Stage & Control loops relationship
The power stage PWM frequency can be adjusted in 4 different frequencies. Each frequency has an associated rate for the control loops, as specified in the following table.
|Power stage PWM frequency||Current loop frequency||Servo loops frequency (position, velocity, commutation & shunt)|
|20 kHz||20 kHz||20 kHz|
|50 kHz||50 kHz||25 kHz|
|100 kHz||50 kHz||25 kHz|
|200 kHz||50 kHz||25 kHz|
