Description of power section parameters
Parameters
Power section parameters \ drive data \ monitoring functions
The following monitoring functions have been implemented to monitor what happens to
drive-specific parameters in the specific application and to be able to react in case of
impermissible deviations. You can set the response to triggered monitoring functions
under "Unit functions/error monitoring".
Speed monitoring
index 8557.0
This parameter is used to activate speed monitoring.
Setting range:
• OFF
• MOTOR MODE
• REGENERAT. MODE
• MOTOR / REGENERATIVE
The speed required by the setpoint can only be achieved if there is sufficient torque
available to meet the load requirements. Once the current limit (index 8518.0) has been
reached, MOVIGEAR
®
assumes that the torque has reached its maximum and the
desired speed cannot be attained. Speed monitoring is triggered if this situation persists
for the duration specified in the delay time (index 8558.0).
Delay time speed
monitoring
index 8558.0
This parameter is used to set the delay time for speed monitoring:
• Setting range: 0 – 1 – 10 s
The set current limit can be reached briefly during acceleration, deceleration, or load
peaks. You can prevent speed monitoring from responding too sensitively by setting the
delay time accordingly. The current limit must be reached permanently for the duration
of the delay time before monitoring responds.
Power section parameters \ drive data \ limit values
Minimum speed
index 8576.0
This parameter is used to set the speed value, the lower limit of which must not be
exceeded even when zero is selected as the setpoint:
• Setting range: 200 – 2000 rpm
• Setting range in conjunction with option /ECR: 0 – 2000 rpm
Maximum speed
index 8517.0
This parameter is used to set the speed value, which cannot be exceeded by a specified
setpoint:
• Setting range: 200 – 2000 rpm
• Setting range in conjunction with option /ECR: 0 – 2000 rpm
If n
min
> n
max
is set, then n
max
applies.
Current limit
index 8518.0
This parameter is used to set the current limit:
• Setting range: 0 – 250 – 400 % I
N
The current limit is given in % IN. It is based on the continuous apparent current of the
power section. The actually effective current limit can be limited to protect the gear unit.
The current limit is visible in the parameter "effective q-current limit".
Effective q-current
limit index 9951.3
The effective q-current limit results from the current limit (index 8518.0) and the limitation
depending on the gear ratio and is indicated in % IN.
