Notes on Commissioning
The content of S-0-0091, Bipolar velocity limit value is the limit for the
maximum allowed velocity and has to be adjusted to the mechanical
properties. When defining this parameter you have to take into account
that all velocity command values are thereby limited to this value. This
has to be taken into consideration when defining the travel profiles (target
position, velocity and acceleration), because an inadmissible lag error can
possibly occur due to the limitation that is taking effect.
Diagnostic and Status Messages
• E2059 Velocity command value limit active
If the resulting velocity command value is within the limit, the E2059
warning is displayed.
• E2063 Velocity command value > limit S-0-0091
Parameter S-0-0036, Velocity command value is limited to the value
of parameter S-0-0091, Bipolar velocity limit value, if the value in
S-0-0036 is higher than the value in S-0-0091. In this case the warning
E2063 is generated.
• F8079 Velocity limit S-0-0091 exceeded
The value of parameter S-0-0040, Velocity feedback value is
monitored. If it exceeds the 1.125-fold value parameterized in
S-0-0091, Bipolar velocity limit value, the F8079 error message is
generated.
Brief Description
To avoid accidents and damages to the machine, many preventive safety
precautions are provided. Part of these safety precautions is the limitation
of the allowed working range (travel range) by the drive. For this purpose,
position monitoring functions and position limitations have been
implemented in the drive.
The travel range monitor (travel range limit
switch or software limit switch) only fulfills the
requirements for protecting machinery, but is
not sufficient for personal protection!
