9 MAJOR POSITIONING CONTROL
9.2.19 Current value changing
When the current value is changed to a new value, control is carried out in which the
"
Md.20
Current feed value" of the stopped axis is changed to a random address set
by the user. (The "
Md.21
Machine feed value" is not changed when the current value
is changed.)
The two methods for changing the current value are shown below.
[1] Changing to a new current value using the positioning data
[2] Changing to a new current value using the start No. (No. 9003) for a current
value changing
The current value changing using method [1] is used during continuous positioning of
multiple blocks, etc.
[1] Changing to a new current value using the positioning data
Operation chart
The following chart shows the operation timing for a current value changing. The
"
Md.20
Current feed value" is changed to the value set in "
Da.6
Positioning
address/movement amount" when the positioning start signal turns ON.

Current feed value changes to the
positioning address designated by the
positioning data of the current value changing.
The above chart shows an example
when the positioning address is "0".

Restrictions
(1) An axis error "New current value not possible" (error code: 515) will occur and
the operation cannot start if "continuous path control" is set in "
Da.1
Operation pattern". ("Continuous path control" cannot be set in current value
changing.)
(2) "Current value changing" cannot be set in "
Da.2
Control system" of the
positioning data when "continuous path control" has been set in "
Da.1
Operation pattern" of the immediately prior positioning data. (For example, if
the operation pattern of positioning data No. 1 is "continuous path control",
"current value changing" cannot be set in positioning data No. 2.) An axis error
"New current value not possible" (error code: 515) will occur and the machine
will carry out a deceleration stop if this type of setting is carried out.
(3) An axis error "Outside new current value range" (error code: 514) will occur
and the operation cannot start if "degree" is set in "
Pr.1
Unit setting" and the
value set in "
Da.6
Positioning address/movement amount" is outside the
setting range (0 to 359.99999 [degree]).
