Description of power section parameters
Parameters
Power section parameters \ setpoints/ramp generators \ speed ramps
Ramp t11 up/down
CW/CCW index
8470.0 8471.0,
8472.0, 8473.0
These parameters are used to set ramp t11:
• Parameter 8470.0 ramp t11 up CW
• Parameter 8471.0 ramp t11 down CW
• Parameter 8472.0 ramp t11 up CCW
• Parameter 8473.0 ramp t11 down CCW
The ramp times refer to a setpoint step change of
∆
n = 3000 rpm. The ramp takes effect
when the speed setpoint is changed and the enable is revoked via the CW/CCW
terminal.
• Unit: [s]
• Setting range: 0 – 2 – 2000 s
Stop ramp t13
index 8476.0
This parameter is used to set stop ramp t13:
• Unit: [s]
• Setting range: 0 – 2 – 2000 s
The stop ramp is active in the event of a power failure or an error (parameterizable error
responses).
Emergency stop
ramp t14 index
8477.0
This parameter is used to set emergency stop ramp t14:
• Unit: [s]
• Setting range: 0 – 2 – 2000 s
The emergency stop ramp is activated in the event of an error (parameterizable error
responses).
The system monitors whether the drive reaches zero speed within the set time. After the
set time expires, the output stage is inhibited and DynaStop
®
is activated (if installed)
even if zero speed has not yet been reached.
Ramp monitoring
index 8928.0
This parameter is used to activate ramp monitoring:
• Setting range: YES / NO
If you set the deceleration ramps to a value that is much shorter than can be physically
achieved in the system, the rotating drive will be stopped once the monitoring time has
expired.
The respective ramp time also has to be increased, if the ramp timeout is definitely
triggered by a preset ramp that cannot be traveled. This parameter is an additional
monitoring function for speed monitoring. However, it only applies to the deceleration
ramp. This means the parameter can be used to monitor the deceleration ramp, stop
ramp or emergency stop ramp if speed monitoring is not desired.
