Chapter 12 Description of Parameter SettingsMS300 (High Speed Model)
12-00-8
It is used to set the source of the operation frequency in AUTO mode.
When the operation command is controlled by the keypad KPC-CC01 (optional), keys RUN,
STOP and JOG (F1) are valid.
Stop Method
Factory Setting: 0
Settings 0: Ramp to stop
1: Coast to stop
The parameter determines how the motor is stopped when the drive receives stop command.
1. Ramp to stop: the AC motor drive decelerates to 0 or minimum output frequency (Pr. 01-09)
according to current set deceleration time and then stop (by Pr. 01-07).
2. Coast to stop: the AC motor drive stops output immediately, and the motor free runs to stop
according to the load inertia.
It is recommended to use “ramp to stop” for safety of personnel or to prevent material from
being wasted in applications where the motor must stop immediately after the drive stops.
The deceleration time has to be set accordingly.
If the motor free running is allowed or the load inertia is large, it is recommended to select
“coast to stop”. For example, blowers, punching machines and pumps.
Control of Motor Direction
Factory Setting: 0
Settings 0: Enable forward / reverse
1: Disable reverse
2: Disable forward
This parameter enables the AC motor drives to run in the forward / reverse Direction. It may be
used to prevent a motor from running in a direction that would consequently injure the user or
damage the equipment.
Memory of Digital Operator (Keypad) Frequency Command
Factory Setting: Read Only
Settings Read only
If keypad is the source of frequency command, when Lv or Fault occurs, the present frequency
command will be saved in this parameter.
