P1.047

Speed reached (DO.SP_OK) range

Default: 10

Unit:

1

1

rpm (rotary)*

mm/s (linear)*

Format: DEC

Control mode: S / Sz

Setting range: 0 to 300

Data size: 16-bit

Address: 015EH

015FH

Settings:

In Speed mode, when the absolute value of the difference between the Speed command and the motor

feedback speed is less than this parameter and this status is kept for the time duration set in P1.049,

the digital output DO.SP_OK (DO: 0x19) is on.

Note: when the difference between the Speed command and the motor feedback speed exceeds the range set in

P1.047, the system recalculates the duration.

No

5. DO.SP_OK is On

6. DO.SP_OK is Off

1. Speed command: the command that you input without acceleration or deceleration, rather than the

command from the front end speed circuit. Its source is from the register.

2. Feedback speed: the actual speed of the motor which has been filtered.

3. Obtain the absolute value.

4. Determine whether the absolute value of the speed difference is smaller than the parameter value. If

you set the parameter to 0, DO.SP_OK is always off. If the absolute value is smaller than the

parameter, the digital output is on, otherwise it is off.

Note: rotary means a permanent-magnet synchronous rotary motor; linear means a permanent-magnet

synchronous linear motor.
