6.5 Velocity and Acceleration Calculation
When the unit mode (axis parameter #255) is set to 1 (which is also the default value), all velocity parameters
on the TMCM-3212 are given in microsteps per second (also called pulse per second or pps). Acceleration
and deceleration units are given in pps
2
.
When axis parameter #255 is set to 0 the internal units of the ramp generators are directly used. But this
is only necessary in very special cases. Normally one should leave axis parameter #255 at 1 and use the
pps units.
In order to convert between pps units and units like rounds per second (rps) or rounds per minute (rpm),
one has to know the fullstep resolution of the motor (full steps per round) and the microstep resolution
setting of the module (axis parameter #140, default setting is 256 microsteps per full step).
So to convert from pps to rps, use the following formula:
v
rps
=
v
pps
r
fullstep
· r
microstep
To convert from rps to rpm, use:
v
rpm
= v
rps
· 60
With the following symbols:
• v
rps
: velocity in rounds per second
• v
rpm
: velocity in rounds per minute
• v
pps
: velocity in pulses (microsteps) per second
• r
fullstep
: fullstep resolution of the motor (with most motors 200 (1.8°))
• r
microstep
: microstep setting of the module (default 256)
So, with a 200 fullsteps motor and a microstep setting of 256 (axis parameter #140 = 8), a velocity of
51200pps will result in 1rps (60rpm).
