The mechanical damping is obtained by the intro-
duction ofaviscous friction between the motor shaft
and the load. The friction system must be elastic
and it willrecover the original relative angular shaft
alignement to assure the correct final positioning.
The response time of the damping system must be
quite fast,and it must be active just for rapid speed
changes otherwise a severe limitation in the maxi-
mum speed willoccur.
The electronic damping is obtained by the proper
driving of the motor phases that are switched on
andoffinsuchawayto generated anegative torque
to decelerate and stop the rotor smoothly. Let’s
assume the motor is moving from position 1 to the
detent position 2, i.e. the phase Ais switched OFF
and the phase B is switched ON.
The rotor starts moving at t
0
instant (see fig. 22),
and after a time t
1
, the phase driving is reversed
(phase A ON and phase B OFF) generating a
braking torque that will allow the rotor to approach
the final detent position at a very limited speed.
Before the zero speed is reached, (t
2
) it is neces-
sary to switch back the phase driving to itsoriginal
condition in order to stop the system at its target
position.
Leaving thephase drivingunchanged willcause the
motor to stop a step earlier of the correct position
because themotor, after the zero speed isreached,
will accelerate in the reverse direction returning to
the starting position.
The deceleration time as well the damping level is
easily adjusted by changingthe timing i.e. t
1
andt
2
,
but it can be quite complicate to compensate a
system where large load variation occurs.
Figure 22. Single Step Response with Damping.
In fact, an heavy load variation causes a large
variation of the single step response time of the
system, and itcould be that asystem compensated
in a no load condition will stop one step behind
when fully loaded, while another compensated at
full load will probably exibits erratic positioning at
no load.
Ifthe loadcondition isknownitispossible tointroduce
a compensation circuit that can be conveniently
driven by one or more User outputs. Fig. 22 shows
the motor response to a single step pulse with elec-
tronic damping and the relative phase driving. This
phase switching reversal method is also known as
the bang-bang damping method,and it canbe easily
implemented by usingthe GS-Cmodule.
The RAMP and MOV signals allow the user to
detect when the last pulses are issued, and to
generate, by a simple logic circuit, the delayed
phase reversalcommands necessary to implement
the sequence of fig. 23.
The circuit uses a last pulsedetector (G1), and on
the falling edge of the Asignal (synchronous to the
last step command), a timing generator istriggered.
The various delays can be trimmed to the values
requested by the operating conditions, and the
pulse sequence reported in figure 23 (A, B and C
signals) in generated.
The Aand Bsignals are used to reverse the motion
direction (G
2
) while the C signal steps twice the
motor (backwardand forward).
