11 RG-MCMET
N2 Points
Point Description
1-20: PID Feedback
This point monitors the current state of the PID Feedback. If the drive is running in Local or
Serial Control Mode, the PID Setpoint will be as dictated by Local PID Cmd. If the drive is
running in Remote Control Mode, the Setpoint will come from either analog source TB-5A
or TB-5B. Refer to the MC3000 Installation and Operation Manual (M301) for more details
on PID functionality.
1-21: Command PID Setpoint
This point monitors the current state of the PID Setpoint. If the drive is running in Local or
Serial Control Mode, the PID Setpoint will be as dictated by Local PID Cmd. If the drive is
running in Remote Control Mode, the Setpoint will come from either analog source TB-5A
or TB-5B. Refer to the MC3000 Installation and Operation Manual (M301) for more details
on PID functionality.
1-22: Actual Speed
This point indicates the speed (in Hz) at which the drive is currently running.
4.3 Binary Input (BI) Point Descriptions
Point Description
2-01: Fault Condition
This point indicates whether or not the drive is currently tripped on a fault. This point
returns 0 (OK) if the drive is not in a fault condition or 1 (FAULT) if the drive is currently
faulted.
4.4 Analog Output (AO) Point Descriptions
Point Description
3-01: Command Speed
This point represents the speed at which the drive is being commanded to run. It is
acquired from the currently selected speed source (preset speeds, speed pot, etc. if set to
auto speed control; keypad if set for manual speed control). Overriding this parameter will
force the drive to operate at the override speed until released. Until the point is released,
the drive will ignore any changes in speed induced by the currently selected speed source.
The value of this point is limited by drive Parameters 10 (minimum frequency) and 11
(maximum frequency). Parameter 10 can be set down to 0.00 Hz. Parameter 11 can be set
up to 120.00 Hz.
3-02: Keypad Command Speed
This point represents the command speed as dictated by the keypad. This speed is only
used if the drive is set for MANUAL speed control. Therefore, overriding this parameter will
only have an effect if MANUAL speed control is selected. The value of this point is also
limited by Parameters 10 and 11.
