on the motor controller. For example, if this value is 1.0 and the read-out limits
are [-10.0 10.0], the EPICS limits are set to [-9.0 9.0]. This parameter uses engineering units (EGU). Defaults to 0.0.
- `CANSETSPEED`: If set to 1, the motor speed can be modified by the user. Defaults to 0.
- `ADAPTPOLL`: If set to any value other than 0, adaptive polling is enabled for this particular axis. Adaptive polling is designed to reduce the communication load in case some axis is moving. By default, if at least one axis is moving, all axes are polled using the busy / moving poll period (see [IOC startup script](#ioc-startup-script)). Adaptive polling modifies this behaviour so that the affected axis is only polled with the busy / moving poll period if it itself is moving. Defaults to 1.

Adaptive polling modifies this behaviour so that the affected axis is only polled with the busy / moving poll period if it itself is moving. This setting is ignored for "forced fast polls" (when the poller is woken up, e.g. after an axis received a move command). Defaults to 1.
