Time-Based Alternation Process Hold Mode Response Time
Program Virtual Linear Pump VLP Time-Based Alternation
During Time-Based Alternation operation, while running in the Process Hold
mode, this parameter sets the time that the system may operate within the
maximum or minimum VLP zones before turning the ASD on or off,
respectively.
Time-Based Alternation Direct Mode Response Time
Program Virtual Linear Pump VLP Time-Based Alternation
During Time-Based Alternation operation, while running in the Direct mode,
this parameter sets the time that the system may operate within the maximum or
minimum VLP zones before turning the ASD on or off, respectively.
Power Running Torque Limit 1
Program Torque Torque Limit Settings
This parameter determines the source of the control signal for the positive
torque limit setting.
If Setting is selected, the value set at
Torque Limit 1 input.
Settings:
1 — V/I
2 — RR
3 — RX
4 — F441 (Setting)
Power Running Torque Limit 1 Level
Program Torque Torque Limit Settings
This parameter provides a value for the Power Running Torque Limit 1
setting if F441 is selected at parameter F440.
This value provides the positive torque upper-limit for the 1 motor.
Regenerative Braking Torque Limit 1
Program  Torque Torque Limit Settings
This parameter determines the source of the Regenerative Torque Limit
control signal.
If Setting is selected, the value set at
Settings:
1 — V/I
2 — RR
3 — RX
4 — F443 (Setting)
168
F441 is used as the Power Running
F443 is used for this parameter.
