The internal control voltage measured.

Encoder
counts
When Reg20, FLWERR, exceeds this limit, bit 1,
FLW_ERR, in Reg35, ERR_STAT, is set and the
motor will stop if Reg22 is non-zero. Usually this value
is set experimentally to detect situations where a
movement is blocked or fails.

Bits to determine what will happen when the main
supply voltage to the motor is below the threshold for
motor operation. Any combination of the following bits
can be set.
Bit 0: Set bit 9, UV_ERR, in Reg35, ERR_STAT.
Bit 1: Perform a controlled stop, then go passive.
Bit 2: Set V_SOLL to zero, do not go passive.
24 FNCERR
(not
present)
Na /
0
Word /
RW
Encoder
counts
Shows how much the motor is behind the ideal
movement; precise operation depends on mode.
When this accumulated value exceeds Reg26,
FNCERRMAX, the FNC_ERR bit is set in Reg35,
ERR_STAT and the motor will stop.
25 P_IST_TURNTAB
(not
present)
Na /
0
Word /
R
- Displays the actual position, like P_IST, but is offset
by N times the rotary table working range so
P_IST_TURNTAB is always between MIN_P_IST and
MAX_P_IST. Used mainly with the Rotary table
option.
26 FNCERRMAX
(not
present)
Na /
0
Word /
RW
Encoder
counts
The limit used with Reg24, FNCERR.
27 TURNTAB_COUN
T
(not
present)
Na /
0
Word /
RW
- Holds a count of the number of times the value of
Reg25, P_IST, wraps around one of its limits,
MIN_P_IST or MAX_P_IST. Used only with the Rotary
table option. Counts up or down depending on the
direction of the wrap around.
28 MIN_P_IST
(not
present)
Na /
0
Word /
RW
Encoder
counts
Used to define and enable the minimum software
position limit, so the motor will stop (and enter passive
mode) if the value of P_IST (the actual position) gets
below this value. If MIN_P_IST is zero, the low
position limit will not be enabled. In Rotary Table
operation, this limit is used as the lower wrap-around
position count.
29 DEGC
(not
present)
Na /
0
Word /
R
-> The temperature measured inside the drive.
Approximately 0.1221 Degree Celsius per count.
30 MAX_P_IST
(not
present)
Na /
0
Word /
RW
Encoder
counts
Used to define and enable the maximum software
position limit, so the motor will stop (and enter passive
mode) if the value of P_IST (the actual position) gets
above this value. If MAX_P_IST is zero, the high
position limit will not be enabled. In Rotary Table
operation, this limit is used as the higher wrap-around
position count
31 DEGCMAX
(not
present)
Na /
690
(84'C
)
Word /
R
- The maximum value of Reg29, DEGC, before the
motor will set the Temperature error bit in ERR_STAT
and change into Passive mode. Same scaling as
Reg29, DEGC.
32 ACC_EMERG
(not
present)
Na /
0
Word /
RW
- Acceleration to use during emergency stops.
