Number / Alarm Cause
A195 -Negative software limit switch position
approached
Negative overtravel
reached -"Software limit switches - negative" (machine
data 12) entered incorrectly
-The programmed position is less than the
negative software limit switch.
-"Reference point - coordinate" (machine data
3) is less than the negative software limit
switch.
-Incorrect encoder actual value
Effect:
The axis movement is stopped via the
deceleration ramp.
A196 -Positive software limit switch position
approached
Positive overtravel
reached -"Software limit switches - positive" (machine
data 13) entered incorrectly¨
-The programmed position is greater than the
positive software limit switch
-"Reference point - coordinate" (machine data
3) is greater than the positive software limit
switch
-Incorrect encoder actual value
Effect:
The axis movement is stopped via the
deceleration ramp.
A200 No position has been programmed in the NC
block for the roll feed version, although the
No position has been axis number of the roll feed is specified.
programmed in
Automatic mode Effect:
NC program execution is inhibited or aborted,
the axis is brought to a standstill via the
deceleration ramp.
A201 The decoded NC block needs a path or axis
velocity.
No velocity has been
programmed in Effect:
Automatic mode NC program execution is inhibited or aborted,
the axis is brought to a standstill via the
deceleration ramp.

SIMOVERT MASTERDRIVES Operating Instructions
Counter-measure
-Check the machine data and the NC program.
-Check the encoder actual value.
-Check the machine data and the NC
programs.
-Check the encoder actual value.
The axis number and the positional value must
be specified in every NC block for the roll feed
version.
When using linear interpolation with path
velocity (G01), a path velocity must be defined
with F. When using chaining with axis velocity
(G77), the axis velocities must be defined with
FX, FY, etc. When using roll feed with axis
velocity (G01), the velocity must be defined
with F.
