6.6 Checking the direction of rotation of the sewing drive CAUTION: Before the special sewing machine is started it is essential to check the direction of rotation of the sewing drive. Switching it on can cause damage if the direction of rotation is incorrect. The arrow on the belt guard indicates the correct direction of rotation. The direction of rotation of the direct-current positioning actuator is set to run from right to left by the pre-set value of the relevant parameter in the control.
6.7 Checking the positioning Needle positions are correctly set prior to delivery, but they should still be checked before starting the machine. NB: The sewing foot must be locked in the up position (see Operating instructions, section 6.13). The machine must move to an intermediate halt in position 1 (needle down). See section 7.1, LED 7. Position 1 – – Turn on the main switch. – Check the position of the needle. Briefly push the pedal forwards and return it to its original position.
7. Operating and adjusting the DC1500/DA220C direct-current positioning actuator Operation The DA220C control contains all operating components necessary to switch functions and set parameters. It can be operated without an operating panel, but seam programming is not possible. The V810 and V820 operating panels (optional equipments) can also be connected to the control. Seam programming can be carried out with the V820 operating panel.

Setting positions 1 and 2 Prerequisite: The reference position has been set (see section 7.1.5, “Setting the reference position”). NB: The position values are pre-set, so there is normally no need to set them. The pre-set values (see the parameter sheet in the accessory kit) are equivalent to the number of increments after the reference position (in the correct direction of rotation). One revolution of the motor shaft is equal to one revolution of the handwheel , equivalent to 512 increments.
7.1.6 Setting machine-specific parameters with the DA220C control 7.1.6.1 General The sewing-drive control functions are determined by the program and the parameter settings. Parameter values are pre-set by the drive manufacturer prior to delivery. For each class and subclass a number of technician-level or even manufacturer-level parameters must be changed so that the control exactly matches the machine. The relevant parameters are listed in table 7.1.6.3 and the parameter sheet (see table 7.1.6.2).
** A function module is a part of the control that handles one of the machine’s facilities, e.g. raising and lowering the transport roller. The control contains two function modules, A and B. Each function module has the following hardware: – – – one output (A or B), e.g. to control a solenoid valve one input ( A or B), e.g. to connect a key one output for an LED (A or B), e.g. displaying a switch status. Each function module can be assigned various functions by the software.
