Setting the PTO Interface

Availability

Available with firmware version ≥V01.04.

Type of Usage of PTO Interface

The PTO interface allows you to make reference value signals from the device externally available.

The PTO interface can be used in several ways:

Encoder simulation based on a position value
Encoder simulation based on reference current
PTI signal

The parameter PTO_mode lets you set the way the PTO interface is used.

Parameter name HMI menu HMI name	Description	Unit Minimum value Factory setting Maximum value	Data type R/W Persistent Expert	Parameter address via fieldbus

Modified settings become active the next time the power stage is enabled. Available with firmware version ≥V01.04.	- 0 0 6	UINT16 R/W per. -	Modbus 1342 IDN P-0-3005.0.31

Encoder Simulation Based on a Position Value

The following types of encoder simulation based on a position value are possible:

Encoder simulation based on actual position of encoder 1
Encoder simulation based on the reference position values (_p_ref)

The resolution for the encoder simulation is set with the parameter ESIM_scale.

Parameter name HMI menu HMI name	Description	Unit Minimum value Factory setting Maximum value	Data type R/W Persistent Expert	Parameter address via fieldbus
ESIM_scale (ConF) → (i-o-) (ESSC)	Resolution of encoder simulation. Resolution defines the number of increments per revolution (AB signal with quadruple evaluation). The index pulse is created once per revolution at an interval where signal A and signal B are high. Type: Unsigned decimal - 2 bytes Write access via Sercos: CP2, CP3, CP4 Setting can only be modified if power stage is disabled. Modified settings become active the next time the product is powered on. Available with firmware version ≥V01.04.	EncInc 8 4096 65535	UINT16 R/W per. -	Modbus 1322 IDN P-0-3005.0.21

The parameter ESIM_HighResolution lets you set the resolution with decimal places.

Parameter name HMI menu HMI name	Description	Unit Minimum value Factory setting Maximum value	Data type R/W Persistent Expert	Parameter address via fieldbus
ESIM_HighResolution	Encoder simulation: High resolution. Specifies the number of increments per revolution with 12 bit decimal places. If the parameter is set to a multiple of 4096, the index pulse will be generated exactly at the same position within one revolution. The setting of parameter ESIM_scale is only used if parameter ESIM_HighResolution is set to 0. Otherwise, the setting of ESIM_HighResolution is used. Example: 1417.322835 encoder simulation pulses per revolution are required. Set the parameter to 1417.322835 * 4096 = 5805354. In this example, the index pulse will be generated exactly after every 1417 pulses. This means that the index pulse shifts with each revolution. Type: Unsigned decimal - 4 bytes Write access via Sercos: CP2, CP3, CP4 Setting can only be modified if power stage is disabled. Modified settings become active the next time the product is powered on. Available with firmware version ≥V01.04.	EncInc 0 0 268431360	UINT32 R/W per. expert	Modbus 1380 IDN P-0-3005.0.50

The phase shift of the encoder simulation is set with the parameter ESIM_PhaseShift.

Parameter name HMI menu HMI name	Description	Unit Minimum value Factory setting Maximum value	Data type R/W Persistent Expert	Parameter address via fieldbus
ESIM_PhaseShift	Encoder simulation: Phase shift for pulse output. The generated encoder simulation pulses can be shifted in units of 1/4096 encoder pulses. The shift results in a position offset at PTO. The index pulse is shifted as well. Type: Signed decimal - 2 bytes Write access via Sercos: CP2, CP3, CP4 Modified settings become active immediately.

Encoder Simulation Based on Reference Current

In the case of encoder simulation based on the reference current, A/B signals are output. The maximum frequency of the A/B signals is 1.6 * 10^-6 increments per second and corresponds to the maximum reference current (value in parameter CTRL_I_max).

With firmware version ≥V01.06, you can set encoder simulation based on the reference current.

PTI Signal

If the PTI signal is selected by means of parameter PTO_mode, the signal from the PTI interface is directly made available at the PTO interface.
