
Target speed unit: 1 [rpm] (Example: +1000 [rpm]

K+1000)

Current speed: Speed at which the motor is running. The units of current speed and
target speed are the same.
*1: The status value is stored in the low-order byte. The high-order byte is always
set to 00.
For the details of each status, refer to (1) of section 11.3.3.3.

The target speed (RWwn) value can be changed while the motor is running. For example,
when the target speed (RWwn) is changed from K+1,500 to K+3,000, the motor speed changes
from 1,500 [rpm] to 3,000 [rpm].

To change the sign of the target speed (RWwn) value (i.e., to reverse the rotation direction of
the motor), set the target speed (RWwn) to K+0, and change the sign of the value after the
motor has stopped (with running output (RXn0) OFF). The motor is stopped if the sign of the
target speed value is changed without this procedure being performed. To recover the motor,
turn OFF the rotation command input (RYn0), and then turn it ON.
