Additional Features
1.
There is a option on the way in which the 2 state (binary) parameters return values when polled. These are accessible
only via the configurable PNOs. If ESP SUPPORT is disabled the data part of the message consists of
>x
where x = 0 or 1. Thus the message length is minimised.
If ESP SUPPORT is enabled the data part of the message consists of
>0 0 0 x
where x = 0 or 1. This option is intended for use with Eurotherm ESP devices. When sending a selection message to
these parameters any leading zeros are ignored.
2.
On the main RS485 serial port (P1) the parity is EVEN by default, but may be switched to ODD using the keypad.

Notes
1.
The reserved bits in these parameters return zero for a poll. The state for a selection is immaterial.
2.
Access to these parameters is read/write if the drive is not running or read-only if the drive is running.
3.
The range of this parameter is restricted as a function of the drive power rating. For Type 5, 6 and 7 power ratings the
switching frequency is limited to 6kHz.
