Settings:
This parameter is used to set the denominator of the electronic gear ratio. The
numerator of the electronic gear ratio is set by P1-44. P2-60 ~ P2-62 are used to set
the additional numberators.
As the wrong setting may cause motor to run chaotically (out of control) and it may
lead to personnel injury, therefore, ensure to observe the following rule when setting
P1-44, P1-45.
The electronic gear ratio setting (Please also see P1-44, P2-60 ~ P2-62):

The electronic gear ratio setting range must be within: 1/50<N/M<25600.
Please note:
1. In PT mode, the setting value of P1-45 can not be changed when the servo drive
is enabled (Servo On).

Format:
Decimal
Settings:
This parameter is used to set the pulse numbers of encoder outputs per motor
revolution.
Please note: When the following conditions occur, the output frequency for pulse
output may exceed the specification and cause that the servo drive fault AL018
(Encoder Output Error) is activated.
f1: Pulse input f2: Position command
N: Numerator, the setting value of P1-44 or
P2-60 ~ P2-62
M: Denominator, the setting value of P1-45
