2 Functions of Devices in DVP-PLC deceleration section. b) When X0 is disabled (i.e. zero return is completed), set M1148 to disable this function. Note: The example offered here is one of the applications. Please adjust the settings of the parameters according to the features of and restrictions on your machines. Function Group PWD Pulse Width Detection Duty-Off/Duty-On Number M1144, D1144 Application: Before the instruction DDRVI is used to drive the servo, the acceleration/deceleration operation is performed on the target position and the target frequency. After the instruction DDRVI is enabled, the operation can not be performed on the same target position and target frequency.
The advantage is that the production can be enhanced. Device: If M1144 is On, the function is enabled. If M1144 is Off, the function is disabled. D1144→Using the index value of the data register For example, k0 represents D0, k100 represents D100. Usage: (Firmware version above 2.0) 1. Suppose the value in D1144 is k0. The value in (D0, D1) represents the number of targets, the value in (D2, D3) represents the target frequency of Y0, the value in D1343 represents the acceleration time, the value in D1348 represents the deceleration time, and the value in D1340 represents the acceleration/deceleration frequency . 2.
When M1144 is ON and the instruction DDRVI is not enabled, the operation is performed on the acceleration/deceleration frequency and the number of targets. After DDRVI is enabled, the pulses are generated. 3. If M1144 is On, the previous output value is executed whenever DDRVI is enabled. If users want to change the target frequency or the number of targets, users have to reset M1144 to Off when DDRVI is disabled. 4. When this function is used, the default acceleration time and deceleration time are the values in D1343 and D1348. Therefore, the acceleration sections and decelerations section can occupy 30 sections respectively. 5.
This function can be used with the designated deceleration number function (D1232, D1233), and the masking/marking function (M1156). Timing chart: 1. The function is disabled: Freq. Freq. Start DDRVI Start DDRVI Time Time Calculation time Calculation time DVP-PLC Application Manual 2-110
