9.6.7 Analogue speed specification (E7) (option not available with COMPAX 1000SL)

Only in COMPAX

XX6X and

COMPAX XX70

Option E7 "Analogue speed specification" is available with COMPAX XX6X "Electronic transmissions" and COMPAX XX70 "Cam controller".

Exception:

In addition, E7 can be used with COMPAX XX00 to implement an external speed specification with the command "SPEED SYNC"; see Page 99 The "Encoder input" option (E2 or E4) cannot be used at the same time as E7.

Using option E7, you can specify a nominal speed value via connector X13 as analogue voltage in the range -10V to +10V. Use 2 digital inputs (PLC level), to define a nominal speed value of 0 and to initiate a change in the rotational direction.

Configuration:

Accuracy

Connection assignment

The following configuration data must therefore be assigned permanent values: P80 = "16" (general drive).

P90 = "1" (mm unit).

P83 = 100000 m (travel per motor revolution).

P93 = "4" (speed control mode).

P143 = 600 000

P144 = "7" (analogue speed specification).

P35 = "1" (transmission factor 1) (I15="0")

I16 = "1" (external nominal value is valid)

These parameters influence the interrelation between voltage and speed; they must therefore be specified and fixed. Specify the required speed directly in P98 in min-1when input voltage is +10V.

Linearity error: <1%

Amplification error: <5% (you can compensate for these with P98).

Offset: <15 mV

Temperature drift: 100 ppm/K
