6.11
Speed error response time
The maximum time is specified here in ms for each axis in which the set limit values of
the speed difference (Parameter
Z
6.5
–
,
Z
6.6
–
) may be exceeded before a drive error
will be triggered.
6.12
Speed actual value > Speed ON threshold
The ON threshold of the free adaptable speed threshold with hysteresis is set here. If the
absolute value of the
Z
18.22
–
Speed actual value exceeds this threshold (
Z
6.12
–
), bit 8
in
Z
18.20
–
Speed controller status is set. The bit will be canceled again if the value falls
below the OFF threshold (
Z
6.13
–
).
6.13
Speed actual value > Speed OFF threshold
The OFF threshold of the free adaptable speed threshold with hysteresis is set here. If
the absolute value of the
Z
18.22
–
Speed actual value is fallen below this threshold
(
Z
6.12
–
), bit 8 in
Z
18.20
–
Speed controller status is canceled. The bit will be set again
if the value exceeds the ON threshold (
Z
6.13
–
).
6.14
Velocity window percentage
The percentage parameter relates to the current speed set value (
Z
18.21
–
). It is used for
generation of the "N
act
= N
set
" message in Speed controller status (
Z
18.20
–
bit 12).

6.20
Blockade speed limit
Standstill threshold for blockage monitoring.
The blockage monitoring detects a block when the speed control is at the current limit and
the drive at the same time at standstill (|Nist| < Blockade Speed Limit).
The threshold for the actual speed under which the drive is assumed to be blocked can
be set under this parameter.
