IDN257 Multiplication Factor 2
The multiplication factor 2 defines the amplifier internal multiplication of an rotary encoder
as an external feedback for the position feedback value 2 (IDN53). If the resolution of
feedback 2 (IDN117) is not a result of 2x, the amplifier may use an additional scaling for
IDN53.
If the master write IDN117 the amplifier calculate automatic the “Multiplication factor 2”
(IDN257), for the external feedback, and an additional scaling factor if necessary, to scale
the external feedback to the rotational position resolution set within IDN79 (refer to
IDN53, 79 and 117). The amplifier also does the automatic calculation for position control
with external feedback.

IDN262 Command: Load Default Values
Loads the manufacturer’s default parameters into volatile memory. The parameters
stored in non-volatile memory remain unchanged. The default parameters allow the
amplifier to operate without problems, but the operation is not necessarily optimized.
This procedure will normally modify the amplifiers startup program, and the amplifier will
re-compile the staretup program and perform a warmstart in the CP4 transition check,
which may take up to 3 minutes. During the warmstart, the LED on the front panel of the
amplifier will flash 3 dots. During the warmstart IDN182 Bit 1 is set, it will cleared after the
warmstart. Alternatively, the serial interface (setup software or terminal program) may be
used to save all values and reset the amplifier before the CP4 transition check procedure
is executed.

IDN264 Command: Back-up Working Memory
This command saves all data essential for amplifier operation from the active memory to
the non-volatile memory. IDN192 defines which data is essential for amplifier operation.
