Bit # Function Comment
0 Reserved
1 Velocity in specified window Velocity in limits as per parameter #59: VAR_VLIMIT_SPEEDWND
2-4 Reserved
5 Velocity at 0 (zero) Velocity 0: Zero defined by parameter #58: VAR_VLIMIT_ZEROSPEED
6,7 Reserved
8 Bus voltage below under-voltage limit
Utilized to indicate drive is operating from +24V keep alive and a valid DC
bus voltage level is not present.
9,10 Reserved
11 Regen circuit is on
Drive regeneration circuit is active. Drive will be dissipating power through
the braking resistor (if fitted).
12-20 Reserved
21 Set if homing operation in progress Drive executing Pre-defined homing function (see section 2.15).
22 Set if system homed Drive completed Pre-defined homing function (see section 2.15).
23
If set then last fault will remain on the
display until re-enabled.
User can set this bit to retain fault code on the display until re-enabled. It is
useful if there is a fault handler routine. When the fault handler is exited, the
fault number on the display will be replaced by current status (usually DiS if
bit #23 is not set). Setting bit #23 retains diagnostics on the display.
24
Set if EIP IO exclusive owner
connection is established. Cleared if
closed.
Checks if drive is controlled by EthernetIP master. Use bit #24 and bit #25 to
process “loss of connection” condition (if needed ) in the user’s program
25
Set if EIP IO exclusive owner
connection times out. Cleared if exc.
owner conn exsists.
Checks if connection with Ethernet/IP master is lost. Use bit #24 and bit #25
to process “loss of connection” condition (if needed) in the user’s program
26-31 Reserved
2.13 Fault Codes (DFAULTS register)
Whenever a fault occurs in the drive, a record of that fault is recorded in the Fault Register (DFAULTS). In addition,
specific flags in the System Status Register will be set helping to indicate what class of fault the current fault belongs to.
Table 18 summarizes the fault codes. Codes from 1 to 16 are used for DSP subsystem errors. Codes above that range
are generated by various subsystems of the PositionServo.
