Page 19: Useful Notes
The long pin on the power board connector J11 represents pin 11 (Axis #2 U phase). If the 3U amplifier is not used in Delta Tau UMAC rack, it is a user’s responsibility to assure that the proper cooling is provided for the IGBTs. Delta Tau suggests a fan capable of at least 100 CFM placed as close to the heatsinks as possible. - Page 20 3U Digital PWM Amplifier User Manual Useful Notes...
