Coupling characteristics
The following characteristics can be defined for every synchronous spindle coupling:
● Block change behavior
The condition to be fulfilled for a block change can be defined on activation of
synchronous operation or on alteration of the transformation ratio or the defined angular
offset when the coupling is active:
– Block change takes place immediately
– Block change in response to "Fine synchronism"
– Block change in response to "Coarse synchronism"
– Block change for IPOSTOP (i.e. after setpoint-end synchronism)
– Check of the synchronism conditions at an arbitrary moment with
WAITC.
● Type of coupling between FS and LS
The position setpoint or the actual position value of the leading spindle can be used as
the reference value for the following spindle. The following coupling types can therefore
be selected:
– Setpoint coupling (DV)
Use in position controlled operation. The control dynamic response of both spindles
should coincide as far as possible. Preferably, the setpoint coupling should be used.
– Actual value coupling (AV)
Application if no position control of the LS is possible or with great deviation of the
control characteristics between FS and LS. The setpoints for the FS are derived from
the actual values of the LS. The quality of synchronism is worse with a varying spindle
speed than with the setpoint coupling.
– Speed coupling (VV)
Internally, the velocity coupling is a setpoint coupling. The requirements for FS and LS
are lower. Position control and measuring systems are not required for FS and LS.
The position offset between FS and LS is undefined.
The selection of the relevant coupling characteristics for the configured coupling is made
using machine data (see Section "Configuration (Page 728)") and for the user d
efined
coupling using the
COUPDEF language command (see Section "Definition (COUPDEF)
(Page 721)").
In addition, couplin
g characteristics Type of coupling and Block change response can be
altered for the permanently configured coupling by means of language command
COUPDEF.
