ABB RHDE250 - Test Values (Brake and Motor); Brake Voltage; Motor Voltage; Winding Resistance

30 RHD250 to 4000 (Contrac) ELECTRICAL ROTARY ACTUATOR | SEI/RHD250/4000-EN REV. A
… 7 Electrical test values
Test values (Brake and Motor)
Brake voltage
DC 135 V with AC 115/AC230 V mains supply.
Motor voltage
Check for currents symmetry (i. e. with clip-on ammeter).
Winding resistance
Depending on the actuator version proceed as follows:
• Open the motor terminal box.
• Refer to the values in table for proper resistance values of
motor and brake windings.
Position of the cable gland may vary; cable numbers are printed
on the cable; terminal no. only for reference purpose (expl.
