Speed Control Section 10-5
The speed command value for speed control is set in units of 0.001% as a
ratio of the Servomotor's momentary maximum rotation speed. (The unit is
different from that used for the speed command value for position control
(command units/s).) The speed command value is specified in the range
−
199.999% to 199.999%, and the rotation direction is determined by the sign
(positive or negative) of the speed command value.
The actual Servomotor speed control range and minimum control unit depend
on the Servo Drive specifications.
To stop speed control, execute DECELERATION STOP or EMERGENCY
STOP. (For details on stop functions, refer to
10-9 Stop Functions .)
Servo Parameter Area G-series Servo Drive Speed Control Parameters
Pn003 is used to select the function of the option command value for speed
control.
The option command value for speed control is described on the following
pages.
Pn062 is set as the detection threshold of the Zero Speed Flag (word b+1, bit
08) in the Axis Operating Input Memory Area. Pn061 is set as the detection
width of the Speed Conformity Flag (word b+1, bit 07) in the Axis Operating
Input Memory Area.
W-series Servo Drive Speed Control Parameters
Pn002.0 is used to select the function of the option command value for speed
control. The option command value for speed control is described in the fol-
lowing pages.
The data length for Pn002.0 is the set value specified to transfer Pn002
(including Pn002.0) when transferring Servo Parameters.
Pn502 is set as the detection threshold of the Zero Speed Flag (word b+1, bit
08) in the Axis Operating Input Memory Area. Pn503 is set as the detection
width of the Speed Conformity Flag (word b+1, bit 07) in the Axis Operating
Input Memory Area.
