Drive Current
Definition: network output SNVT_amp nvoDrvCrnt
Explanation: Provides the drive output current in amps.
Drive Speed
Definition: network output SNVT_level_percent nvoDrvSpeed
Explanation: Provides the speed of the drive as a percentage of the nominal
speed. Since nominal speed and nominal frequency are tightly
connected, the output value is calculated on the nominal (base)
frequency and the running (output) frequency. This variable is
used as a heartbeat to monitor the health of the LonWorks
communication interface. See section 7.3 for information about
heartbeats.
Drive Power
Definition: network output SNVT_power_kilo nvoDrvPwr;
Explanation: Provides the drive power in kilowatts. The LonWorks module
sets this at start up. Note that VTAC 7 parameter P.066
(Network Output Register 1 Source) must be set to 0.
Drive Voltage
Definition: network output SNVT_volt nvoDrvVolt
Definition: Provides the drive voltage in volts.
Operation Hour Counter
Definition: network output SNVT_time_hour nvoDrvRunHours;
Explanation: Total power-on time in whole hours. Since drive report by days
(?), this will have a granularity of 24 hours.
OCL Loop Output
Definition: network output SNVT_lev_percent nvoOCL_loop_out
Explanation: Provides OCL Loop output from the drive. The LonWorks
module sets this at start up. Note that VTAC 7 parameter P.068
(Network Output Register 3 Source) must be set to 8.
