7-6-3 Other precautions related to control mode switching
• After servo-off (including alarm state), counter clear or deceleration and stop according to drive inhibit input, the
control mode in the servo driver is forced to change to PP and internal position command generation process is
forced to
stop.
For example, if the main power is turned off in CV status, servo is turned off and internal status is switched to PP.
Result: status and monitor data that rely on control mode will be switched to position control instead of velocity
control.
• When command is NOP (0
h), or if cyclic command is not correctly received due to command error or
communication error, the previous command mode will be maintained. Note that commands (command velocity
etc.) to servo driver will not be disabled. For NOP command, refer to 7-1-2, for command error, refer to 6-10, and
for communication error, refer to 6-11.
• When communication cycle is 0.0833 ms or 0.1666 ms, generation of response data (e.g. position deviation)
depending on control mode will delay. For details, refer to 3-1-3 and 3-1-4.
• For communication cycle/command update cycle, 16-byte mode/32-byte mode and combination of compatible
control modes, refer to 2-5-1. If unsupported combination is selected, it will cause Err91.1 (RTEX command error
protection) and command error (002Eh).
• When selecting another control mode (cyclic command), wait for at least 2 ms. When several control modes are
repeatedly switched within 2 ms, Err91.1 (RTEX command error protection) and command error (002Eh) will
occur.
• When homing command (
4h) except for latch mode is being executed, do not change control mode. Before
changing control mode, be sure to perform homing process and select the normal command (
0h). Follow the basic
switching method described above.
• When Block Diagram of 2 Degrees of Freedom Mode is disabled,. do not change control mode other than position
control mode. When control modes were changed, Err91.1 (RTEX command error protection) and command error
(002Eh) will occur.
