Delta RMC151 - Manual (Page 969)

9 Register Reference
Type: Axis Parameter Register
RMC70 Address: %MDn.125, where n = 12 + the axis number
RMC150 Address: %MDn.125, where n = 24 + the axis number
System Tag: _Axis[n].SimWeight, where n is the axis number
How to Find: Axes Parameters Pane, All tab: Simulate
Data Type: REAL
Units: lb
Range: >0
Default Value: 1000
Description
The simulator weight parameter is the weight of the mass that the system is moving. This
weight is used when calculating the acceleration forces of the simulator.
Changing this Parameter
For best results, always change this parameter only from Axis Tools. If the axis is in
Simulate mode, and this parameter is changed, simulate model will be suspended until
the last simulate mode parameter register (Max Compression [Fx:127]) has been
updated. At this point, the new simulator model will be calculated and the simulator
model will be activated. When the simulator model is suspended, the Actual Position will
not move.
Certain simulator settings may result in an invalid model. If this occurs, change your
settings. See the Simulating Motion topic for more details.
9.2.2.3.10. Maximum Force (Simulator)
Type: Axis Parameter Register
RMC70 Address: %MDn.126, where n = 12 + the axis number
RMC150 Address: %MDn.126, where n = 24 + the axis number
System Tag: _Axis[n].SimMaxForce, where n is the axis number
How to Find: Axes Parameters Pane, All tab: Simulate
Data Type: REAL
Units: lb
Range: >0
Default Value: 10000
Description
This parameter specifies the maximum force of the system. The simulator simulates the
force it takes to accelerate and move the system (based on the Weight parameter) and
also simulates the spring force at the Positive Physical Limit and Negative Physical Limit.
The maximum force will limit the maximum acceleration of the axis. It will also affect the
max speed of the axis, similarly to a hydraulic system.
At the Positive and Negative Physical Limits, the simulator simulates a spring force that
extends outside the limit by the distance specified by the Maximum Compression
parameter. The Maximum Force specifies the max force at the max compression. The
spring force increases linearly from zero at the limit to the max force at the max
compression. This is useful for simulating pressure or force control.
