9 MAJOR POSITIONING CONTROL
9.2.21 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.
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]).

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".
