Command pulse input range: 1 / 4<Nx / M < 262144.
For the E-Gear ratio setting, please refer to Section 6.2.5.
Note:
1. Do not change the setting in the Servo On state.
2.
In direct 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
reconstruction of the absolute coordinate system, so you must re-do the homing procedure. If you do not want
P1.045 to be reset to the default value, please set P3.012.Z to 1. For details, please refer to P3.012.
P1.046 ▲ Encoder pulse number output
Address: 015CH
015DH
Default: 2500 Control mode: All
Unit: Pulse Setting range: 20 – 320000
Format: DEC Data size: 32-bit
Settings:
The number of single-phase pulse outputs per revolution; the maximum output frequency of the
hardware is 19.8 MHz.
Note: the following circumstances may result in exceeding the maximum allowable output pulse frequency of the drive,
causing AL018:
1. Encoder error
2. The motor speed is faster than P1.076
3.

P1.047 Speed reached (DO.SP_OK) range
Address: 015EH
015FH
Default: 10 Control mode: S / Sz
Unit: rpm Setting range: 0 – 300
Format: DEC Data size: 16-bit
Settings:
When the deviation between the Speed command and the motor feedback speed is less than this
parameter, the digital output DO.SP_OK (DO code 0x19) is on.
