Capacitor
(C1)
The ripple current load for C1 depends on the motor’s operating point and the power supply output capacity.
Under worst case conditions however, the ripple current may reach I
cont
/ 2. Use capacitors with rated
voltage ≥63 V and adequate ripple current to avoid overheat or life time reduction.
Example for C1 worst-case dimensioning:
I
cont
= 5 A  Rubycon (63YXJ470M12.5X25); 470 μF, 63 V, 1990 mA r.m.s.
Capacitor
(C2)
To avoid voltage overshoot at power plug-in with a separately sourced logic supply, use an electrolytic
capacitor covering the following requirements: 33 μF or 47 μF, 63 V, at least 265 mA r.m.s.
• Rubicon (63ZLH47MEFCTA6.3X11) or (63YXJ47M6.3X11)
• Panasonic (EEU-FR1J470B)
• Nippon Chemicon (EKYB630ELL330MF11D) or (EKY-630 ELL330MF11D)
