6-11 MHT258a (Engl.)
■ Speed command gain (63) / Torque command gain (65)
These gains can be set from ±0.10 to ±1.50 times in increments of 0.01.
Specifying the negative sign can invert the rotational direction.
■ Speed command offset (64)
This can be set from –2000 to + 2000 in increments of 1. The setting value has no unit. The initial value has been set at factory shipment
individually. Automatic offset adjustment is enable in the trial operation mode by the keypad panel ([
]). The value after
adjustment will be saved in the system para.64.
■ Torque command offset (66)
This can be set from –200 to + 200 in increments of 1. The setting value has no unit. The initial value has been set at factory shipment
individually. Automatic offset adjustment is enable in the trial operation mode by the keypad panel ([
]). The value after
adjustment will be saved in the system para.66.
The terminal function of speed command [NREF] and torque command [TREF] terminal can be selected.
System parameter 60 to 62
Para. Name Setting range Initial value Change
60 Torque command function select 0: Torque command 1: Speed command (aux.) 0 Power
61 Speed limit select 0: Parameter 1: Speed command terminal 0 Power
62 Torque limit select 0: Parameter 1: Torque command terminal 0 Power
■ Speed limit select (system parameter 61)
Selects the motor speed limiting method in torque control.
Setting Description
0: Parameter Limits the speed by basic para. 16.
1: Speed command terminal Limits the speed by the speed in response to the input voltage to speed command terminal.
When “1: Speed command terminal” is selected, gain and offset can be adjusted by system para. 63 and 64.
■ Torque limit select (system parameter 62)
Selects the motor output torque limiting method. Torque limit is effective in speed control and position control.
Setting Description
0: Parameter Limits the output torque by basic para. 59.
1: Torque command terminal Limits the output torque by the torque in response to the input voltage to torque command terminal.
When “1: Torque command terminal” is selected, gain and offset can be adjusted by system para. 65 and 66.
When “0: Parameter” is selected, the setting of basic para. 59 is always effective.
In torque control mode, the setting of basic para. 59 is always effective. In torque control, the function of the torque command terminal does
not change.
The torque limit (30) signal is assigned to the control input terminal, the basic para. 59 setting and the motor’s maximum torque can be
changed over. If the torque command is selected by the system para. 62, the motor torque can be selected between the maximum torque
and the one in proportion to the torque command terminal voltage.
・Where the torque limit (30) is not assigned to the control input terminal.
The setting of basic para. 59 is always effective.
・Torque limit (system parameter 62 : 0: Parameter)
Torque limit (30) Torque limit value
OFF Motor max. torque
ON Basic para. 59 setting value.
