5. PARAMETERS

5.2.3 S-pattern acceleration/deceleration

In servo operation, linear acceleration/deceleration is usually made. By setting the S-pattern acceleration/deceleration time constant (parameter No.14), a smooth start/stop can be made. When the S- pattern time constant is set, smooth positioning is executed as shown below. When the S-pattern acceleration/deceleration time constant is set, the time from a start to the output of Movement complete (PED) increases by the S-pattern acceleration/deceleration time constant.

	Acceleration time	Deceleration time

	Ta Ts	Tb

Ta: Time until preset speed is reached

Tb: Time until stop

Ts: S-pattern acceleration/deceleration time constant (parameter No. 14)

Setting range 0 to 100ms

5.2.4 Analog output

The servo status can be output to two channels in terms of voltage. Use this function when using an ammeter to monitor the servo status or synchronizing the torque/speed with the other servo.

(1)Setting

Change the following digits of parameter No.17:

Parameter No. 17

Analog monitor 1 (MO1) output selection (Signal output to across MO1-LG)

Analog monitor 2 (MO2) output selection (Signal output to across MO2-LG)

Parameters No.31 and 32 can be used to set the offset voltages to the analog output voltages. The setting range is between 999 and 999mV.

Parameter	Description	Setting range [mV]
Parameter No.31	Used to set the offset voltage for the analog monitor 1 (MO1) output.		999 to 999
Parameter No.32	Used to set the offset voltage for the analog monitor 2 (MO2) output.
