Error flags

Bit 1: motor has been stopped due
to encoder deviation error
These two flags are cleared after
reading.

1/2/3

212

Maximum encoder
deviation

When the actual position (param. 1)
and the encoder position (param.
41) differ more than the value set
here, the motor will be stopped.
Setting this parameter to 0 disables
this function.

Units to use for velocity and
acceleration:
0: use TMC457 units
1: use PPS units

Parameter / symbol

Unit

Calculation / description / comment

CLK

[Hz]

clock frequency of the TMC457 in [Hz]

[s]

second

microstep

fullstep

velocity v[Hz]

microsteps / s

v[Hz] = v[457] * ( 2 * f

CLK

[Hz] / 2^31 )

acceleration a[Hz/s]

microsteps / s^2

a[Hz/s] = a[457] * f

CLK

[Hz]^2 / (16*256) / 2^30

micro step resolution USR
(used U instead of µ for micro)

counts

micro step resolution in number of microsteps
(i.e. the number of microsteps between two
fullsteps)

v[FS] @ USR

US/s

v[FS/s] = v[US/2] / USR
USR



microstep resolution

a[FS/^2] @ USR

US/s^2

a[FS/s^2] = a[US/s] / USR

ramp_steps[457] = rs

[457]

rs = 2 * (v[457])^2 / (a[457]) / 2^18
micro steps during linear acceleration ramp
(if v_max is really reached during acceleration)
