Range selection
S2:1 together with S1 are used for setting the tripping frequency level at normal speed.
S2:4 together with S3 are used for setting the tripping frequency level at ESR speed.
If ESR is not used, set S2:4 + S3 equal to S2:1 and S1.
Pulse frequency can be calculated from formula = Motor rpm x Pulses per rev / 60
Example
Normal use
A 3000 rpm motor with 32 pulses per
revolution has a full speed pulse
frequency of 1600 Hz.
Suitable maximum overspeed
detection level is 1600Hz + 25% =
2000Hz.
On the table the highest value under
2000Hz is 1902Hz. Suitable switch
settings are
S2-2=OFF and S2-3=OFF
S2-1=OFF and S2-4=OFF
S1=F and S3=F
Check from V4.8.1 that the detection
level is 1902Hz/1600Hz =118,9% of
nominal speed.
ESR use
If ESR is applied for 150% of nominal
speed, then the full ESR pulse
frequency is 1,5 * 1600Hz = 2400Hz.
Suitable maximum overspeed
detection level is 2400Hz + 25% =
3000Hz.
S2-2=OFF and S2-3=OFF are
according to normal speed settings.
On the table the highest value under
3000Hz is 2793Hz.
Correct switch settings are S2-4=ON
and S3=4.
Check from V4.8.2 that the detection
level is 2793Hz/2400Hz =116,4% of
ESR speed.
Encoder with 600 ppr or over needs both encoder channels connected.
