Procedure
1. Select the desired function indicated
by a "CO"-parameter.
2. Set the parameter p0771 of the analog
output to the value of the "CO"-
parameter.
Use parameter p0776[0] for setting a voltage or current output.
Set the following parameters for releasing STO:
p0010 = 95 Enter commissioning of fail-safe functions
p9761 = ... Enter password for fail-safe function (factory setting = 0)
p9762 = ... Enter new password, if required (0 ... FFFF FFFF)
p9763 = ... Confirm new password
p9601.0 = 1 STO is selected via terminal strip
p9659 = ... Set the forced checking procedure timer.
To fulfill the requirements of standards ISO 13849-1 and
IEC 61508 regarding timely error detection, the converter must
regularly test its safety-relevant circuits to ensure that they
function correctly.
p9700 = D0 Copy fail-safe parameters
p9701 = DC Confirm fail-safe parameters
p0010 = 0 Finish commissioning of fail-safe functions
Examples
Function
: AO 0 provides the "current"
signal.
