6.17.3 Analog Outputs

In the standard setting, the values of the Pt 100 inputs are taken over with a

change rate of 1 K/s. The disadvantage here is that for large changes in

temperature it can take a long time until the correct temperature reading is

attained. For example, it would take 30 seconds to correctly read a

temperature change of 30 K. An advantage of this, however, is a low

sensitivity to disturbance: the temperature display will not jump back and forth

between two values:

If you wish to work with a change rate of 1 K/s, set MP4020 bit 7 = 0.

If you wish to accept the values of the Pt 100 inputs immediately, set

MP4020 bit 7 = 1.

PLC compatibility

Bit 7: Transferring the values of the Pt 100 inputs

0: Accept values at a change rate of 1 K/s

1: Accept results immediately

You can drive analog outputs 1 to 13 at sockets X8 and X9 (See "Mounting and

Electrical Installation" on page 3 – 5).

Every analog axis or analog spindle needs an analog output. These outputs

are no longer available to the PLC.

With this module you place an analog voltage on an analog output. The voltage

is output with a slight delay after the end of the PLC scan.

Call the module only once for each output per PLC scan!

Format: 1 mV

Voltages greater than +10 V or less than –10 V are limited to the respective

maximum value.
