ASDA-A3
P1.045▲
Default: 100000
Unit: pulse
Format: DEC
Settings:
If the setting is incorrect, the servo motor is prone to sudden unintended acceleration. Follow these
instructions.
E-Gear ratio setting: f2 = f1 ×
Range of E-gear ratio: 1 ＜ Nx / M ＜ 262144.
For the E-Gear ratio setting, refer to Section 6.2.5.
Note:
1. Do not change the setting in the Servo On state.
2. In communication mode (DMCNET / CANopen / EtherCAT), if you cycle the power to the drive, the E-Gear
ratio is set to the default value of the communication protocol. Resetting to the default value results in the re-
establishment of the absolute position system, so you must re-do the homing procedure. If you do not want
P1.045 to be reset to the default value, set P3.012.Z to 1. For details, refer to P3.012.
P1.046▲
Default: 2500
Unit: pulse
Format: DEC
Settings:
Rotary motor: the number of single-phase pulse outputs per revolution; the maximum output frequency
of the hardware is 19.8 MHz.
Linear motor: the number of single-phase pulse outputs per meter; the maximum output frequency of
the hardware is 19.8 MHz.
For the OA and OB settings of CN2 and CN5, refer to P1.074.Y (Selection of OA/OB output source) and
P1.097 (Encoder output denominator (OA, OB)).
Note:
In the following circumstances, pulse output of the encoder may exceed the maximum allowable output pulse
frequency of the drive, causing AL018 or AL048:
1. Encoder error.
2. The motor speed is faster than P1.076.
3. Rotary motor: if P1.074.Y = 0 and P1.097 = 0, motor speed (rpm)/60 x P1.046 x 4 > 19.8 x 10
Linear motor: if P1.074.Y = 1 and P1.097 = 1, motor speed (m/s) x P1.046 > 19.8 x 10
