6.6.4.7 Object 0x5610: Z pulse enable
If this flag is set, the valve is waiting for the next Z pulse. When the Z pulse appears, the predefined position
<ZPulseSet> (0x5612) is copied to the <EncoderValue> (0x5613) and <ZPulseEnable> (0x5610) is reset to
indicate the successful referencing. Only if the <DeviceMode> (0x6042) is switched to 1 or 2 (setpoint input
via bus or locally).
6.6.4.8 Object 0x5612: Z pulse set
This is a predefined position. It will be copied to the <EncoderValue> (0x5613), if a Z pulse appears while
<ZPulseEnable> (0x5610) is set. Only if the <DeviceMode> (0x6042) is switched to 1 or 2 (setpoint input via
bus or locally).
6.6.5 SSI encoder
The SSI encoder sends an absolute position to the valve. For communication the valve needs two parame-
ters, the <BitSize> (0x6243) and <BitRate> (0x561F).
6.6.5.1 Object 0x5620: Master slave
Only the SSI master interface is supported.
Value description
6.6.5.2 Object 0x6243: Bit size
This parameter sets the number of bits which have to be sent to the valve (the size of the SSI telegram). It de-
pends on the type of the transducer.
