70 Program features
Overspeed protection (parameter
The user can set overspeed limits by specifying a margin that is added to the
currently-used maximum and minimum speed limits.
Ramp stop supervision (parameters
)
The control program has a supervision function for both the normal and emergency
stop ramps. The user can either define a maximum time for stopping, or a maximum
deviation from the expected deceleration rate. If the drive fails to stop in the expected
manner, a fault is generated and the drive coasts to a stop.
Main cooling fan supervision (parameter
)
The parameter selects how the drive reacts to a loss of the main cooling fan.
With an inverter unit consisting of frame R8i inverter modules, it may be possible to
continue operation even if a cooling fan of an inverter module stops. See the
description of the parameter.
Custom motor current fault limit (parameter
The control program sets a motor current limit based on drive hardware. In most
cases, the default value is appropriate. However, a lower limit can be manually set by
the user.
Local control loss detection (parameter
)
The parameter selects how the drive reacts to a control panel or PC tool
communication break.
