Multiple Axes Simultaneous Activation; Detection Of Absolute Position; All Module Reset When A Stop Error Occurs - Mitsubishi Electric MELSEC iQ-F FX5 User Manual

Precautions
• Where the system starts the remaining distance operation after changing the positioning address under the relative address
specification, positioning operation is performed with the current address at start of the positioning or table instruction as
the basis.
• After the interrupt input signal 1 is detected, the table operation instruction becomes unable to execute the remaining
distance operation (Control system [6: Interrupted stop (relative address specification), [7: Interrupted stop (absolute
address specification)].
• For positioning instructions or control methods of the table operation that are not compatible with the remaining distance
operation, only deceleration stop is performed. The operation ends with an error. For the PLSV/DPLSV instruction and
table operation instruction (control method: [4: Variable Speed Operation] or [5: Table Transition Variable Speed
Operation]), after the deceleration stop the operation ends normally.
• When the operation is stopped by other than the pulse decelerate and stop command remaining distance operation
enabled is ON, the operation ends with an error. (Page 80 Pulse output stop)

Multiple axes simultaneous activation

Tables for up to 4 axes can be activated at the same time with the DRVMUL instruction. Continuous operation can be
performed. (Page 193 Continuous operation) After the operation is started, each axis operates independently, thus, table
shift timing during continuous operation does not need to be considered.
Precautions
• The axes to be driven simultaneously must be from the same module. (Example. The combination of axis 1 and axis 2 in
the CPU module and axis 5 and axis 6 in a high-speed pulse input/output module is not allowed.)
• 2 axes can be simultaneously driven for the high-speed pulse input/output module.

Detection of absolute position

The absolute position (ABS) data of the servo amplifier can be read with the DABS instruction.
For the absolute position detection operation, refer to Page 155 Outline of operation.

All module reset when a stop error occurs

When the system intends to stop the pulse output but fails to do so due to a bus error, this function resets all the extension
modules while immediately stopping the pulse output. (Page 60)
For supported versions for all module reset when a stop error occurs, refer to Page 251 Added and Enhanced Functions.
In addition, all modules are reset when the following conditions are satisfied.
• All module reset instruction (SM4210) is turned ON
• F5F5H (reset permission code) is stored in the all module reset instruction permission code (SD4210)
Precautions
An error occurs when stop by reset. To restart operation of the extension module, turn the power of the CPU module from off
to on or reset the system.
