Product description
The universal vector controller for frequency control of B503PRO series products.
Features
Programmable digital input: 7 digital input terminals, one of which supports high-speed pulse input up to 100kHz
Programmable analog input: AI1, AI2: 0V~10V voltage input or 4mA~20mA current input
Open collector output: 1 output
Relay output: 2 outputs
Analog output: 2 outputs, AO1 supports 0mA~20mA current output or 0V~10V voltage output, AO2 supports 0mA~20mA current output
Product advantages
• Frequency setting methods: digital setting, analog setting, pulse setting, serial communication setting, multi-speed setting, simple PLC setting, PID setting, etc., which can realize the combination of settings and mode switching sleep Function: Automatic sleep without water, better energy saving effect
• Built-in PID control function
• Simple PLC, multi-stage speed control function: control terminals to achieve up to 16-stage speed control
• Traverse Control Function
• Instantaneous power failure non-stop function
• Speed tracking and restart function: realize smooth start without impact on the rotating motor
• User-Defined Key Function: user-defined multi-function shortcut keys
• Automatic voltage adjustment function: when the grid voltage changes, it can automatically keep the output voltage constant
• Provides multiple fault protection functions: overcurrent, overvoltage, undervoltage, overtemperature, phase loss, overload, and other protection functions
Product parameters
Input voltage range: 380V±15%
Input frequency range: 47Hz~63Hz
Output voltage range: 0V~input voltage
Output frequency range: 0Hz~600Hz
Control mode: vector control without PG, V/F control, torque control (vector control without PG)
Overload capacity:
G type machine: 150% rated current 60s; 180% rated current 3s
P type machine: 120% rated current 60s; 135% rated current 3s
Starting torque: G type machine: 0.5Hz/150% (SVC); P type machine: 0.5Hz/100%
Speed regulation ratio: 1:100 (SVC)
Speed control accuracy: ±0.5% of maximum speed (SVC)
Carrier frequency: 0.5kHz~16.0kHz
