(5)Feed gear n/m
2084 n for flexible feed gear
2085 m for flexible feed gear
1) For serial pulse coder A or B, and serial a pulse coder.
NOTE
For serial pulse coder B, use a value not exceeding 250,000
as the number of feedback pulses per revolution.

NOTE
1 NS is the number of position feedback pulses per one
revolution of the motor (multiplied by four)
