KEB Info Specifications of the HSP5-Interface
Specification HSP5-interface
The HSP5-interface is used for the connection of an F5-operator, PC or other equipment to an
inverter/servo of the unit series COMBIVERT F5. The following properties are defined:
Plug-in connector on the control board D-Sub-9 Female, pin assignment see table 2
Plug-in connector at the operator D-Sub-9 Male, pin assignment see table 3
Level voltage supply VDC
Level signal lines and VDC (TTL)
Telegram access Inverter : full duplex, max. outstanding
acknowledgements
Operator : half duplex, outstanding acknowledgement
Data format serial asynchronous, data bits, Start-, Stop bit,
even parity
Possible baud rates see table 4, unit-dependent
Handshake time T min: us before the start bit, max: unspecified
Handshake time T min: us after the stop bit, max: unspecified
Minimum time between two telegrams T default us, required value can be readout, if
necessary, over inverter parameters
Telegram structure see protocol description HSP5 as well as service
description KEB protocols.

The interfaces are connected by direct plug-on 1:1. Because of the sensitive TTL-level and the high baud
rates extension cables without line driver are not permissible.
The voltage supply for external units (operator/converter cable etc.) can be provided by the control board.
The baud rate of the control board amounts to.4 Kbaud after switch on and can be adjusted with the
parameter SY. (address Bh) depending on the used control board. (Values see table 4)
Minimum time between two telegrams T3 in microseconds can be readout at newer control boards. For
that purpose parameter SY. (address h) must be adjusted first by writing onto the value. Now
the time can be readout over the parameter SY. (address h).
