I have now the R90H drives. Decided on the 200 volt/40 amp drives because according to the people who knows running R990H on over 90 vdc have only 10% margin of getting ruined from overvoltage.
Also have the E2 single-ended encoders, ttl or open collector type from USdigital.
I've read somewhere along this Forum that such type of encoder will have problem with noise especially in industrial environment. Is this true? |
