Basic Parameters

Speed Limit

Designate the applicable maximum speed. All the speed in sequence program or position data must be lower than this parameter. Otherwise, the axis error will be issued.

PSnnX module has different speed resolution according to the configuration of this parameter.

Speed Limit	Resolution (pulse)
1 ~ 8,000	1
8,001 ~ 16,000	2
16,001 ~ 40,000	5
40,001 ~ 80,000	10
80,001 ~ 160,000	20
160,001 ~ 400,000	50
400,001 ~ 800,000	100
800,001 ~ 1,000,000	200

This resolution table is applied to all speed data, such as bias speed, positioning command in sequence program, OPR speeds and so on. Speed data must be multiple of resolution value of above table. If the speed value used is not multiple of resolution value, PSnnX will choose automatically the near most value among the multiple of resolution. But, if the selected speed is lower than bias speed, the bias speed will be selected.

Bias Speed

This parameter designates the initial speed of pulse output. The bias speed has to be defined to allow the motor to start smoothly especially when a stepping motor is used. A stepping motor will not start smoothly if a low rotation speed is instructed at the beginning. This speed cannot be set higher than speed limit.

Acceleration / Deceleration Time (0~3)

Acceleration time specifies the time for the speed to increase from zero to the speed limit value. And deceleration time specifies the time for the speed to decrease from the speed limit value to zero. In normal case, the positioning speed is lower than the speed limit value, thus the actual acceleration/deceleration time will be relatively short. The actual time for acceleration/deceleration can be calculated by following formula.

T = V x Ts / Vmax

V : Destination Speed,
Ts : Acc/Dec time in parameter
Vmax : Speed limit in parameter

Pulse Output Mode

Set the pulse output mode to match the servo amplifier being used. Pulse output signal is specified by the ‘pulse output logic’ parameter setting also. Followings are based on ‘high active’ setting of ‘pulse output logic’ parameter.

PLS/DIR mode

Forward run and reverse run are controlled with the ON/OFF of the direction sign (SIGN).

CW/CCW

During forward run, the forward run feed pulse (CW) will be output.

During reverse run, the reverse run feed pulse (CCW) will be output.

Rotation direction setting

Set the relation of the motor rotation direction and current address increment/decrement.
