Our application is very slow, we calculated our input to the DM1182 driver is 306 pulses for every revolution of the step motor.
When we configure the software for 306 Pulse/Round, we believe that the motor is moving, but very slow!
It seems that if we change the configuration from 306 Pulse/Round to 200 Pulse/Round, with the same input frequency, the motor rotates faster. This is the opposite that we would expect.
Does anyone have suggestions?
Any thoughts on why we are seeing this?

Hi jacoe2222,

Let's make a simple calculation. if a same input frequency ( 1000Hz ), and then
306 Pulse/Round: 1000÷306= 3.3rps
200 Pulse/Round: 1000÷200= 5 rps
That's why the motor rotates faster when you set 200 pulse/round.
Does this solve your problem?
Thanks.
