For linear motors:
Pole_Pitch
Motor_Speed[SI] = ×Motor_Speed[IU]
resolution×T
where:
resolution
–
is the motor position resolution
T
–
is the slow loop sam
pling period expressed in [s]. You can read this value in the “Advanced”
dialogue, which can be opened from the “Drive Setup”
Pole_Pitch
–
is the magnetic pole pitch NN (distance expressed in [m])
6.12.3. Step motor open-loop control. No feedback device or incremental encoder
on load
The internal motor speed units are motor µsteps / (slow loop sampling period). The correspondence
with the motor
speed in SI units is:
] IU [ Speed _ Motor
T steps _ No steps _ No
] SI [ Speed _ Motor

where:
No_steps
–
is the number of motor steps per revolution
No_µsteps
– is the number of microsteps per step. You can read/change this value in the “Drive
Setup” dialogue from EasySetUp.
T
– is the slow loop sampling period expressed in [s]. You can read this value in the “Advanced”
dialogue, which can be opened from the “Drive Setup”
6.12.4. Step motor closed-loop control. Incremental encoder on motor
The internal motor speed units are motor encoder counts / (slow loop sampling period). The
correspondence with the load speed in SI units is:
] IU [ Speed _ Motor
T lines _ encoder _ No
] SI [ Speed _ Motor
