Start Frequency/Stop Frequency; Run/Stop Control With Frequency Setting Signals - Toshiba TOSVERT VF-AS1 Instruction Manual

6.7.1 Start frequency/Stop frequency

 : Start frequency setting
 : Stop frequency setting
• Function
The frequency set with the parameter  is put out as soon as operation is started.
Use the  parameter when a delay in response of starting torque according to the
acceleration/deceleration time is probably affecting operation. Setting the starting frequency to a value from
0.5 to 2.0Hz (max. 5Hz) is recommended. The occurrence of an overcurrent can be suppressed by setting
this frequency below the rated slippage of the motor. If 0 speed torque is needed (=), set ,
 at 0.0Hz.
• At start up : frequency set with  is put out immediately.
• At stop

6.7.2 Run/Stop control with frequency setting signals

 : Operation start frequency
 : Operation start frequency hysteresis
• Function
The Run/Stop of operation can be controlled simply with frequency setting signals.
