Comments:
m Bits 0 to 2:
The internal processing sequence of the bits is as follows:
1. Blocking of positive or negative set values (Bit 0 or 1)
2. Polarity reversal of current set value (Bit 2)
m Bit 6:
The speed synchronization is activated as standard by Z110.2– Mode Bit 6 = 0.
It acts when the ramp function generator is activated, e.g., by changing over or activat-
ing operating mode -3 (speed control), so that no jump in speed occurs.
When it is activated, the ramp function generator initializes its output to the current ac-
tual speed and controls the output to its input value according to the preset ramp.
If Bit 6 is set, the ramp generator output will not be synchronized to the current actual
speed when the ramp generator is activated.
m Bit 7:
If the bit is set, the ramp function generator output Z110.3– decelerates to 0% in the
quick stop time Z110.8–, which was set.
If the trapezoidal speed profile (Z110.2– Mode bit 4 = 0) is set, the set quick stop time
is only valid for the non smoothed curve. The braking time is delayed with smoothing
(Z110.11– Smoothing > 0) depending on the value of the set smoothing
If the S-Curve profile (Z110.2– Mode bit 4 = 1) is set, it is decelerated with trapezoidal
speed profile at quick stop. A set smoothing is not effected.
m Bit 8:
If bit 8 is set, a stop at the deceleration ramp is set at active hardware limit switch and
at active limit switch monitoring (Z121.1– bit 1 = 1). This requires that either the error
message is deactivated via Z110.2– bit 9 = 1 or the error reaction „no reaction“ is set.
The following description is true for the activated error message (Z110.2– bit 9 = 0.
At crossing of a hardware limit switch the error code 906 „Negative hardware limit
switch active“ or 907 „Positive hardware limit switch active“ is set. The following behav-
ior of the drive corresponds to the preset error reaction for the respective error code.
The default value for this error is „no reaction“.
n „No reaction“ and Bit 8 = 0:
Only the respective error is set. New set values from the ramp function generator
input are accepted furthermore. The correspondent reaction must be carried
through the controller. The error can be reset not before a velocity in the „free“ di
-
rection is existent at the ramp function generator output Z110.3–. If the hardware
limit switch is still active and it will be stopped again or driven in the blocked direction
the error message will be sent again.
n „No reaction“ and Bit 8 = 1:
Among the error message a stop is set additionally. The deceleration occurs with the
delay set in
Z110.7– ramp-down time. Set values over the ramp function generator
input are ignored. After the termination of the stop (velocity set value at Z110.3– out-
put of the ramp function generator = 0) the errors of the limit switch may be reset.
After this it may be driven in the „free“ direction. If the hardware limit switch is still
active and it will be driven in the blocked direction again the error message will be
sent again. The blocked direction is displayed in
Z110.1– Status Bits 18 and 19.
