Information
Selection
Response (USR-
MONSELR) Contain the type of monitor information that is applicable to the value
stored in IL††20 (Servo Drive User Monitor Information).
0 to F
25 Machine Coor-
dinate System
Reference Po-
sition (MPOS) IL††18
-2 31 to 2 31 -1
This parameter is the reference position in the machine coordinate sys-
tem and is basically the same value at IL††02 (CPOS). This position
data cannot be refreshed if IB††170: Machine Lock ON.
27 Not used. IL††1A − −
29 POSMAX
Monitor
(PMAXTURN) IL††1C
1 to 2
31
-1
Indicates the infinite length axis reset position (POSMAX) at motion
fixed parameter No. 23.
31 Number of
POSMAX
Turns
(PMAXTURN) IL††1E
-2
31
to 2
31
-1
The count at this parameter goes up and down every time the reset
position (POSMAX) for the infinite length axis at motion fixed
parameter 23 is exceeded. The parameter can be preset with
OL††30: Preset Number of POSMAX Turns and with OB††2D1:
Request for Preset Number of POSMAX Turns.
33 Servo Driver
User Monitor
Information
(USRMON) IL††20
-2 31 to 2 31 -1
Indicates the MECHATROLINK servo monitor information specified
in bits 12 to 15 of OW††2D.
35 Alarms
(ALARM) IL††22 This parameter is valid in Position Control Mode when an OW††20: Motion Command
Code is used. Alarm data and a halt to operation are indicated if this register shows any-
thing other than “0.” The register can be cleared by starting up OB††006: Alarm Clear.
If an alarm occurs, the SVB Modules indicators will indicate (
) . The bit configuration
is described below.
Bit 0 SERVOPACK
Error
(SVERROR) Turns ON when a SERVOPACK alarm is detected.
For alarm details, refer to IW††24.
Bit 1 Positive
Overtravel
(OTF) Turns ON when the positive overtravel signal is input and a move
command is executed in the positive direction.
Bit 2 Negative
Overtravel
(OTR) Turns ON when the negative overtravel signal is input and a move
command is executed in the negative direction.
Bit 3 Positive
Software Limit
(SOTF) Valid if IB††156: Zero Point Return Completed turns ON when the
positive software limit is enabled and an infinite length axis is
selected.
„ OW††20: Motion Command Code Interpolation
This bit turns ON when IL††18: Reference Position in Machine
Coordinate System + OL††26: Stopping Distance
≥ Positive
Software Limit (motion fixed parameter No. 27).
„ OW††20: Motion Command Codes Positioning, Feed, or Step
This bit turns ON when IL††18: Reference Position in Machine
Coordinate System
≥ Positive Software Limit (motion fixed param-
eter no. 27).
