m Bit 9: Speed profile of the ramp generator
This bit is used to set the speed profile for the ramp generator. The ramp generator is
active with the virtual master axis and speed synchronization processes.
m Bit 12: Virtual master axis - Handling the speed set value of the virtual master
axis
If bit 12 is set to 0, the value in Parameter Z145.10– Virtual master speed set value is
routed through the ramp generator of the synchronous operation to the transmission
input. Parameters
Z145.7– to Z145.9– apply as profile data. The profile type is set in
the Z145.2– Mode bit 9.
If bit 12 is set, the speed set value is immediately routed to the transmission input with-
out ramp generator. Optionally, an interpolation can also be activated for the speed set
value. When the interpolation is active, the result will be a set value at the transmission
input that is delayed by an interpolation interval of - 1 ms.
The interpolation interval setting is entered in Z145.11– Virt. master set value cycle
time.
m Bit 13: Real master axis: Setting of the set value source
This bit only relevant a double axis units. The set value of the master axis is here avail-
able. The master axis must be at least in a speed controlled operating mode. If this is
not the case, the actual value of the master axis is used as set value. Although at a
single axis unit or a mono unit the actual value of the master axis is used as set value
for synchronous operation.
145.3 Gear slave axis revolutions
Counter in the transmission ratio i of the electronic transmission.
The input of 0 is rejected and the old value remains effective. The control word bit 8 must
be used to stop the slave axis.
145.4 Gear master axis revolutions
Denominator in the transmission ratio i of the electronic transmission.
The transmission ratio of the electronic transmission function is calculated according to
the equation:
The denominator and counter of the transmission ratio consist of whole numbers without
decimal places. The counter may become negative. The function of a reverse transmis
-
sion can thereby be implemented.
