System description
1.1.3 Compatibility to Eurotherm- 3 U analog regulator ESR AC S
(Not required for new projects)
The digital servo drives are to a great extent pin- and function compatible
to the analog devices of the ESR AC S series.
The EASYRIDER
<
software allows the adaption to your existing equipment
( refer to: Chapter 3 Operating modes)
Further adaptions can be done by solder-jumpers ( refer to: Chapter 7.1 Jumper)
Compatibility restrictions:
Restriction
1 External current limiting
due to analog input at X10.19
In the PC configuration menu the function speed regulator parameter (freely scaled) can be
activated. In few cases the internal Pull-Up resistor with ESR AC S was loaded with an external
Pull-Down resistor in order to reach a current limiting. The Pull-Up resistor on the DER+K
DER can be activated via the solder strip
JP101 .
2 Incremental encoder output-zero offset
With ESR AC S a zero drift was possible by means of DIP switch. This function is not realized
with DER+K DER.
Incremental signal with pulse interval.
3 Temperature monitoring output T2
(only with ESR AC S with corresponding option circuit) T2 is no more signalized.
4 Reference potential
all digital in- and output signals on X10 are referred to X10.9
5 Temperature monitoring PTC
(only with ESR AC S with corresponding option circuit)
Before switching off for approx 3 seconds "WARNING" is signalized.
6 Reset
Connector X10.2 is no more assigned with reset function.
7 n/I-Switch over
Connector X10.11 is not reference potential for n/I-switch over anymore, but X10.9.
8 Warning
Connector X10.7 is not reference potential for warning output anymore, but X10.9.
9 The max. operating voltage on all signal outputs of X10 is DC 45V DC
10 Pin 26 on X50 is not assigned internally and must be free !
One cannot completely rule out the possibility that with special designs of ESR AC S devices
additional adjustments have to be made.
1.1.4 Compatibility to series APOLLO 2G
Output power 5V DC / 150mA for encoder via decoupling diode at X40.9.
Incremental signal with pulse interval.
Compatibility restrictions:
Furthermore, there are no compatibility restrictions.
