F3.13~F3.16 define the relevant parameters of Jog

operation.

As shown in Fig. 5-19, t

and Dec time respectively. t

is the interval of Jog operation(F3.14); f

operating frequency(F3.13).

Actual Acc time t

can be determined by the following

formula, so does the actual Dec time t

Fig. 5-19 Jog operating parameters

Interval of Jog operation (F3.14) is the interval from the

time when the last Jog operation command is ended to

the time when the next Jog operation command is

executed.

The jog command sent during the interval will not be

executed. If this command exists until the end of the

interval, it will be executed.

Note:

1. In Jog operation process, the drive starts according to

starting mode 0 and stops according to stopping mode 0.

The unit of Acc/Dec time is second.

2. Jog operation can be controlled by panel, terminals and

serial port.

F3.17 Acc time 2 Range: 0.1~3600s(min) 【 6.0s/20.0s 】

F3.18 Dec time 2 Range: 0.1~3600s(min) 【 6.0s/20.0s 】

F3.19 Acc time 3 Range: 0.1~3600s(min) 【 6.0s/20.0s 】

F3.20 Dec time 3 Range: 0.1~3600s(min) 【 6.0s/20.0s 】

F3.21 Acc time 4 Range: 0.1~3600s(min) 【 6.0s/20.0s 】

F3.22 Dec time 4 Range: 0.1~3600s(min) 【 6.0s/20.0s 】

Three kinds of Acc/Dec time can be defined, and the

drive's Acc/Dec time 1~4 can be selected by different

combinations of control terminals, refer to the

introductions of F7.00~F7.07 for the definitions of

terminals used to select Acc/Dec time.

Note:

1. Acc/Dec time 1 is defined in F0.10 and F0.11.

2. For the drive of 30kW or above, its factory setting of

Acc/Dec time is 20.0s.

F3.30~F3.35 define the output frequency that will cause

resonant with the load, which should be avoided.

Therefore, the drive will skip the above frequency as

shown in Fig. 5-2020. Up to 3 skip frequencies can be

set.
