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.
