5-40 Understanding IMC-S/23x Setups
Publication 999-122 - January 1997
While the servo output limit is specified in volts (assuming use of
voltage format servo output), it functions equally well with current
format servo output. If this axis is configured for current format servo
output, the actual servo output limit can be calculated as shown below.
For example, if the servo output limit is specified as 8.2 volts but the
axis is configured for current format servo output, the actual servo
output limit is 123 mA, as shown below.
Drive Fault Input
The IMC-S/23x provides a dedicated drive fault input for each physical
axis. These inputs may be connected to fault outputs on the servo
amplifiers (if provided) to notify the IMC-S/23x of a fault in the
amplifier itself.
If you are using the drive fault input, the "contact configuration" of the
amplifier’s drive fault output must be specified. Select
NORMAL OPEN
drive fault contacts if your amplifier activates the drive fault input when
a fault occurs. Select
NORMAL CLOSED drive fault contacts if your
amplifier deactivates the drive fault input when a fault occurs.
Editing the Positioning
Configuration After editing the servo configuration, the IMC-S/23x asks
Toggle to YES and press ENTER to set up the positioning configuration
for this axis.
Position Lock Tolerance
The Position Lock Tolerance value specifies how much position error
the IMC-S/23x tolerates when giving an axis locked indication
(
LOCKED displayed in the status field of the Standard Operator
Interface). As such, it is one of the factors which determines positioning
accuracy. Enter a value in position units for this axis equal to the desired
positioning accuracy of the axis and press ENTER.
