Do not proceed until the
encoder checks out properly.
Running a system with a
disconnected or improperly
connected encoder may
cause the motor to run away.
5.1.3.2 S1 DIP Switch Settings
S1 is used to set the maximum encoder frequency. Setting this switch correctly will improve the low speed
performance. Maximum encoder frequency is affected by the maximum velocity the motor needs to run in
your application and the number of encoder lines. The frequency can be calculated as follows:
Max Frequency = (Max velocity in RPM) *
(lines per rev) / 60
Set S1 so that the frequency supported is at least 50% higher than calculated to allow for overshoot and
other conditions that may cause the motor to go faster than expected. If S1 scales the signal for too low a
frequency or if the motor goes faster than planned even for a short time, the velocity monitor may saturate,
causing the motor to run away.
Scaling the velocity
incorrectly may cause the
motor to run away!
Use Table 3.1 to set S1. Allow
at least 50% margin when
selecting the maximum
frequency.

S1 sets the tach monitor (J201-5 and -6) scaling. The values in Table 3.1 provide settings that scale the tach
monitor to approximately
±
10 VDC at full speed.
5.1.3.3 S2 DIP Switch Settings
Switches S2-1 to S2-3 are used to set the velocity loop integrator value. The more switches set, the lower
the loop response will be. See Figure 5-1 on page 5-8 for detail of the switch circuit.
