We recommend the use the highest possible voltage to supply the motor.
In general the motor torque from a MIS/MIL is not affected by the supply voltage at
speeds below 100RPM but at higher velocities the torque will be very influenced by the
supply voltage (P+ terminal).
Additionally, higher voltage gives better current and filter regulation and thereby better
performance. If there is a tendency for motor resonance, a lower supply voltage can be
a solution to the problem.
Below an example showing the torque curve for the MIS232S
As seen the torque and power stay high up to much higher speeds when using 72VDC
supply compared with 24 or 48VDC.
