Chapter 7 Servo Parameters
Revision June 2010
7-35
Display Format: Decimal
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):
f1
f2 = f1 x

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

GR3 Encoder Output Pulse Number Address: 015CH, 015DH
Default: 2500 Related Section: N/A
Applicable Control Mode: ALL
Unit: pulse
Range: 20 ~ 40000
Data Size: 32-bit
Display 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.
Condition 1: Encoder error.
Condition 2: Motor speed is above the value set by parameter P1-76.
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
