PTO Configuration

Overview

2 PTO channels can be configured on the controller.

Hardware Configuration

Each PTO channel configured uses to 2 fast transistor outputs and 2 digital inputs.The PTO function is only available on controllers supporting fast transistor outputs..

Open the Configuration Window

Step	Action
1	In the Devices tree, double-click MyController > Embedded Functions > PTO_PWM.
2	Select the PTO x tab corresponding to the channel to be configured.
3	The instance of the PTO is created, it can be renamed in the Variable field. Default names are: PTO00 and PTO01.

Step

Action

Select the PTO x tab corresponding to the channel to be configured.

The instance of the PTO is created, it can be renamed in the Variable field.

Default names are: PTO00 and PTO01.

Configuration Window Description

This table describes each parameter available when the embedded PTO_PWM is configured in PTO mode:

Parameter		Value	Default Value	Unit	Description
Mode		PTO	PTO	-	The Mode selected is PTO.
Output Mode		Pulse/Direction Direction/Pulse ClockWise/CounterClockWise CounterClockWise/ClockWise	Pulse/Direction	-	Mode of generation of outputs
Acceleration/Deceleration	Acc./Dec. Unit	ms Hz/ms	ms	-	Acceleration/Deceleration Unit
	Acc. max.	20...65000	20	-	Acceleration rate maximum value
	Dec. max.	20...65000	20	-	Deceleration rate maximum value
	Dec. Fast Stop	20...32500	100	-	Deceleration rate used in case of a fast stop. (Drive Ready input low, limits exceeded, detected errors)
Frequency	Start	0...65535	0	Hz	Start frequency. 0 = no use of start frequency parameter.
	Stop	0...65535	0	Hz	Stop frequency. 0 = no use of stop frequency parameter.
	Maximum	1...100000	100000	Hz	Maximum frequency
Auxiliary Inputs	AUX	Not used Drive Ready Origin	Not used	-	Specific input dedicated to the Drive Ready information or to the reference point detection (origin)
	AUX Filter	0.02 0.4 1.2 4	0.02	ms	Filtering value reduces the effect of bounce on the auxiliary input
	PROX	Disabled Enabled	Disabled	-	Specific input dedicated to the Proximate input
	PROX Filter	0.02 0.4 1.2 4	0.02	ms	Filtering value reduces the effect of bounce on the proximate input
Homing	Homing Acc.	20...65000	500	ms	Acceleration during homing (≤ Acc. max.)
Homing	Homing Dec.	20...65000	500	ms	Deceleration during homing (≤ Dec. max.)
Software Limit	Minimum	-2147483648... 2147483647	-2147483648	-	Minimum software limit)
Software Limit	Maximum	-2147483648...2147483647	2147483647	-	Maximum software limit)

Configure a PTO Channel

Step	Action
1	Enable the PTO channel: In the list box Mode parameter > select PTO.
2	In the list box Output Mode parameter > Select the Mode of generation of outputs in the value column.
3	Configure the Acc./Dec. Unit, Acc.max, Dec. max, and Dec. Fast stop parameters.
4	Configure the Frequency (= Velocity) parameters (Start, Stop, and Maximum).
5	Enable the AUX input.
6	Configure the AUX input filtering value (if enabled at step 5).
7	If you have selected Origin in AUX input, then configure the Homing Acceleration/Deceleration parameters.
8	Enable the PROX input if you need, and select the PROX Filter for it.
9	Configure the Minimum and Maximum value for Software Limit.

The configuration defined can be viewed as a configuration profile:

An error is detected because the Dec. Fast Stop rate is greater than the Dec. max. as it appears in this diagram.
