Position command execution
demand When RY(n 2) is turned on, the next station number set in the
remote register RWwn 4 is set.
When it is set to the servo amplifier, the respond code
indicating normal or error is set to RWrn 2. At the same time,
Position command execution completion (RX(n
＋
2)0) turns
ON.
Refer to section 3.6.3 for details.
RY(n 2)0
Speed command demand When RY(n 2)1 is turned ON, the point table No. or speed
command data set to remote register RWwn 6 is set.
When it is set to the servo amplifier, the respond code
indicating normal or error is set to RWrn 2. At the same time,
Speed command execution completion (RX(n
＋
2)1) turns ON.
Refer to section 3.6.3 for details.
RY(n 2)1
Internal torque limit selection Turning RY(n 2)6 OFF makes the torque limit value of
parameter No.PA11 (forward rotation torque limit) parameter
No.PA12 (reverse rotation torque limit) valid, and turning it ON
makes that of parameter No.PC35 (internal torque limit). (Refer
to section 16.3.2 (3))
RY(n 2)6
Proportion control When RY(n 2)7 is turned ON, the speed amplifier is switched
from the proportional integral type to the proportional type.
If the servo motor at a stop is rotated even one pulse by an
external factor, it develops torque in an attempt to compensate
for a position shift. When the shaft is locked mechanically after
Movement completion (RXnC) is turned OFF, for example,
turning Proportion control (RY(n 2)7) ON as soon as
Movement completion (RXnC) turns OFF allows control of
unnecessary torque developed in an attempt to compensate for
a position shift.
When the shaft is to be locked for an extended period of time,
turn Internal torque limit selection (RY(n 2)6) ON
simultaneously with Proportion control (RY(n 2)7) to make the
torque not more than the rated torque using Internal torque
limit (parameter No.PC35). RY(n 2)7 *
Gain switching When RY(n 2)8 is turned ON, the load inertia moment ratio
and the corresponding gain values change to the values of
parameter No.PB29 to PB34. To change the gain using
RY(n 2)8, make the auto tuning invalid. RY(n 2)8
Position/speed specifying
system selection Select how to give a speed command. (Refer to section 3.6.3.)
OFF: RY of CC-Link-based speed specifying system
Specifying the point table No. with Point table No.
selection (RYnA to RYnE) gives a speed command.
ON : Remote register-based speed specifying system
Setting the instruction code to the remote register
(RWwn 4 to RWwn 6) gives a speed command.
Set the parameter No.PC30 (direct specification
selection) to "
1 ".
