Technical Manual for EA350 Analog Pulse Type Servo Driver V101 8.7 P2-xx Speed control parameter Sketch of speed command: Parameter functions: Select speed command source 1: P2-00=0 : Digital speed setting (set by P2-01) P2-00=1: AI1 setting; P2-00=2: AI2 setting; Important: When P2-00=1: Speed command 1 When P2-00=2: Speed command 1 P2-00=3 : Multi-segment speed switching (see description of group P9); P2-00=4 : Pulse input, speed command 1 = input pulse frequency (kHz)*1000/P2-15. 1. Both the analogs AI1 and AI2 are of ±10V input. P2-01 setting can be positive or negative. The sign of speed command 1 is determined by the product of these two (Two negatives make a positive). 2.
When pulse input is used, the pulse frequency is the square wave frequency input from the PULS port. a) When P1.01 is set to 0 or 1, direction of the speed command 1 depends on speed pulse input via the PULS port and the level input via the SIGN port. b) When P1.01 is set to 2 or 3, value of the speed command 1 depends on pulse frequency input via the PULS port, and direction of the speed command 1 depends on phases of PULS and SIGN. 3. When P1.01 is set to 0 or 1, if speed pulses are wrongly connected to the SIGN port, the motor may be unable to run or may jitter, while the driver may be unable to operate. 4.
For the pulse input frequency, the lowest value 0.1kHz and the highest value is 200kHz. Caution ☞ Parameter functions: In the speed control mode, set the target motor speed and direction; the positive indicates the forward direction. When the analog input is used as the speed command source, this parameter can be interpreted as the analog gain, i.e. the speed command value when the analog equals 10V. For example, if P2-00=1 and P2-01=1,000, the speed command 1 will be 500rpm forward when AI1 is 5V, and 1,000 rpm negative when AI1 is -10V.
Caution ☞ The final speed command is set by P2-12, the final speed is limited by the maximum rotating speed (P0-02), and the rotating direction is determined by P0-01. 141 P2-00 Speed command source 1 option Initial value 0 Communication address 0200H Unit - Time of taking effect With immediate effect Setting range 0~4 Data size 16bit Control mode S P2-01 Digital speed setting 1 Initial value 100 Communication address 0201H Unit rpm Time of taking effect With immediate effect Setting range -30000~30000 Data size 16bit Control mode S
