7.4.1 Recorder Sequencing: Programming, Launching and
Uploading Data
In order to activate the recorder, it must first be programmed to indicate which signals
should be recorded, at what resolution and what will trigger the recording event. A number
of limitations apply to programming the recorder:
The recorder cannot be programmed while it is armed or recording. It must first be
stopped, or “killed” (RR=-0).
Modifying the recorder programming invalidates any previously recorded data. Be sure
to upload all data that you need before programming the recorder.
After it is programmed, the recorder can be launched by:
RR=1
Arms recorder to trigger at next start of motion
RR=2 Starts
recording immediately
RR=3
Arms recorder to start recording at next trigger event
To poll the status of the recorder, use the RR and SR commands. After the recorder data is
ready, use the BH command to upload the data.
7.4.2
Signal Mapping
The recorder can record a range of different signals. The first 16 signals — listed in the
following table — are compatible with other Elmo drives.
Signal
ID
Signal Name
(Command)
Length;
Type
Description
1 Main
speed
(VX)
Long
Float
Speed of main feedback sensor, in
counts/second.
2
Main position (PX)
Long
Integer
Cumulative position of main
feedback sensor, in counts.
3
Position command (DV[3])
Long
Integer
Position reference, in counts. When
external reference mode is set
(RM=1), this signal also includes
analog reference command.
4
Digital input pin status
Short
Integer
IP variable (see IP in the
SimplIQ
Command Reference Manual).
5
Position error (PE)
Long
Integer
Position tracking error: the
difference between main position
reference and main position
feedback, in counts.
6 Current
command
(DV[1])
Short
Float
Current reference to current
controller, in amperes.
7
DC bus voltage
Short
Integer
Bus voltage, in volts.
8
Auxiliary position (PY)
Long
Integer
Cumulative position of auxiliary
feedback sensor, in counts.
