0 The frequency of command pulse input is
more than 1.2 times the setting in Pr5.32.
2 Division and multiplication ratio which are
set up with the command pulse counts
per single turn and the1st and the 4th
numerator/denominator of the electronic
gear are not appropriate.
0
The output frequency of pulse
regeneration has exceeded the limit.
0 Positional deviation of encoder pulse
reference has exceeded 2
0
Input photocoupler of both or one of
safety input 1 and 2 is OFF.
0 Input signals (SI1, SI2, SI3, SI4, SI5) are
assigned with two functions.
1
Input signals (SI6, SI7, SI8, SI9, SI10)
are assigned with two functions.
2 Input signals (SI1, SI2, SI3, SI4, SI5) are
assigned with undefined number.
3
Input signals (SI6, SI7, SI8, SI9, SI10)
are assigned with undefined number.
Check the command pulse input for
frequency.
Check the setup value of electronic gear.
• Check the setup values of Pr0.11 and 5.03.
• To disable the detection, set Pr5.33 to 0.
• Check that the motor runs as per the
(536870912). position command pulses.

• Check that the output toque has not
saturated in torque monitor.
• Make a gain adjustment.
• Set up maximum value to Pr0.13 and
Pr5.22.
• Make a wiring connection of the encoder as
per the wiring diagram.
Check wiring of safety input 1 and 2.
Allocate correct function to each connector
