Number Axis Parameter Description Range [Units] Default Access
180 smartEnergy
actual current
This status value provides the actual
motor current setting as controlled by
coolStep. The value goes up to the CS
value and down to the portion of CS
as specified by SEIMIN. Actual motor
current scaling factor: 0. . . 31: 1/32,
2/32, . . . 32/32
0 . . . 31 0 R
181 smartEnergy
stall velocity
Velocity from which stop on stall fea-
ture is active
0 . . . 4999999 0 RW
182 smartEnergy
threshold
speed
Above this speed coolStep becomes
enabled.
0 . . . 4999999
[pps]
0 RW
184 Random TOff
mode
Enable / disable random TOff mode.
0 - Chopper off time is fixed
1 - Chopper off time is random
0 . . . 1 0 RW
185 Chopper syn-
chronization
This parameter allows synchroniza-
tion of the chopper for both phases of
a two phase motor in order to avoid
the occurrence of a beat, especially at
low velocities. 0: chopper sync func-
tion chopSync off 1. . . 15: chopper
synchronization
0 . . . 15 0 RW
186 PWM threshold
speed
The stealthChop feature will be
switched on when this parameter is
>= 0 and the actual velocity is higher
than this value.
0 . . . 4999999
[pps]
0 RW
187 PWM gradient Velocity dependent gradient for PWM
amplitude (stealthChop). Setting this
value to 0 turns off stealthChop.
0 . . . 15 0 RW
188 PWM
amplitude
Maximum PWM amplitude when
switching to stealthChop mode. Do
not set too low. Values above 64 rec-
ommended.
0 . . . 255 0 RW
189 PWM scale Actual PWM amplitude scaler
(255=max. Voltage). In voltage mode
PWM, this value allows to detect a
motor stall.
0 . . . 255 0 R
190 PWM Mode Status of StealthChop Voltage PWM
Mode (depending on velocity thresh-
olds).
0 - StealthChop disabled
1 - StealthChop enabled
0 . . . 1 0 R
