Settings for the slave drive
5. Configure digital
frequency input X8. The recommended setting value has been checked metrologically by Lenze.
l C0491 = 0; Configuration of signal direction at X8 = digital frequency input
l C0421 = 5 V; set voltage supply encoder at X8.
– 5V for TTL level
l C0420 = 2048; set encoder increments X8
– Same number of increments as for the digital frequency output of the
master (C0030) or the master encoder.
l C4060 = xxx inc; set speed−proportional angular offset for the electrical shaft.
The settings depends on the set output function of X8 in the master C0540:
– C0540 = 1 in the master: C4060 = 15500 inc
– C0540 = 2 in the master: C4060 = 2200 inc
6. Set the positioning
profile for electrical shaft
operation and stretch
factor. l C3095 = 30; et positioning profile mode to "E−shaft via digital
frequency (X8)".
l C3097 = 1000 / C3098 = 1000 ; set stretch factor numerator and denominator
for the electrical shaft (e.g.: 1000 / 1000)
Notes:
l Negative values in the numerator C3097 cause a reversal of direction of
rotation.
l The machine parameters C1202 and C1203 for the gearbox ration are only
effective for positioning and do not influence the drive function "electrical
shaft".
7. Save settings with mains
failure protection. l C0003 = 1; save parameter set 1 safe against mains failure.
The settings for the slave drive are now completed.
Make the same settings for each slave drive in the drive system (from 5th).
In order to put the drive system into operation, the following actions must be carried out:
ƒ Enable the slave drives by the master control (PLC) (
¶ 241)and start the positioning
profile with the setting profile mode = electrical shaft ("E−shaft") ( ¶ 226).
ƒ Enable the master drive by the master control (PLC) and start the corresponding
positioning profiles (
¶ 226).

Tip!
For test purposes, the control interface can be set to "control via codes" with
C4010 = 3. Then the control bits of the "Ctrl1" control word can be defined in
GDC via C4040 to control the drives without a master control.
