Unit Description
14 GEARF1 Gear
factor
Input
Na /
2000
Word /
RW
- The nominator used to scale / gear pulses from an
external encoder/source. Used in gear modes.
15 GEARF2 Gear
Output
Na /
500
Word /
RW
- The denominator used to scale / gear pulses from an
external encoder/source. Used in gear modes.
16 I2T Motor
Load
(mean)
Na /
0
Word /
R
- The calculated power dissipated in the motor, and thus
an approximated value for the rise in temperature inside
the physical motor.
See also I2TLIM (Reg 17).
MacTalk value is calculated as
[%]=I2T/I2TLIM x 100
17 I2TLIM
(not
present)
Na /
100000
Word /
R
- The limit for the value of Reg16, I2T, where bit 0,
I2T_ERR, in Reg35, ERR_STAT will be set and the
motor will change into passive mode.
18 UIT
Regen
-
Rative
Load
Na /
0
Word /
R
The calculated power dissipated in the internal power
dump/brake resistors, and thus a way to estimate their
rise in temperature.
See also UITLIM (Reg 19)
MacTalk value is calculated as
[%]=UIT/UITLIM x 100
19 UITLIM
(not
present)
Na /
2322
Word /
R
The limit for the value of Reg18, UIT, where bit 3,
UIT_ERR, in Reg35, ERR_STAT will be set and the
motor will change into passive mode.
20 FLWERR Na /
0
Word /
RW
Encoder
counts
A measure of how far the drive is from its ideal
regulation goal. This value is calculated differently in
the various modes, and can mean things like ‘pulses
from theoretical position’ or ‘difference in actual velocity
to V_SOLL’. Contact JVL for more detailed information
for specific modes.
21 U_24V Na /
0
Word /
R
The internal control voltage measured.
22
FLWERRMAX
Na /
0
Word /
RW
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.
23
UV_HANDLE
- Set
error bit
- Go to
passive
- Set
velocity
to 0
Na /
0
Word /
RW
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
FNCE
RRMAX
(not

Na /
0
Word /
RW
Encoder
counts
The limit used with Reg24, FNCERR.
27 TURNTAB_COUNT
(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.
29
DEGC
(not
present)
Na /
0
Word /
R
- The temperature measured inside the drive.
