Drum Motor
Options and accessories
Encoder type RM44-RLS for i-series
Output: Incremental, RS422A 5 V, Push-Pull 24 V
The resolution INC in increments per drum revolution can be calculated as
follows:
INC = p x i
p = Number of encoder pulses per rotor revolution
i = Gear ratio of drum motor
Technical data
Hint
The signal sequence of A and B depends on the gear ratio of the drum motor.
Therefore the rotation direction can be different for drum motors with the same
number of poles and power but different speed. In this case the signal cables A
and B can be interchanged.
