I have a regen unit of different brand that supplies 600vdc (for a 400vac system).
Iis it possible to run a 890-system with this dc bus of 600vdc instead of the normal 720vdc and also mix with drives of different brands?
What's the reason for the high 720v dc bus? Is it intended for very dynamic servo applications?
The 600vdc will be less stressful for the motors.
